I remember a long time ago, my mother would add something called 'bluing' when she was washing whites. I asked her why and she said blue makes whites look whiter.
yup detergents automatically do this nowadays
Same here. I remember (talking early 60s) white clothes being immersed for a certain time in water with a blue dye dissolved in it, then left to dry under the sun. This was supposed to make them whiter.
@@coriscotupi Yeah, same time period for me.
@@mhtweeteryep. This has been a thing for a long time alr. I remember back in prob grade3 or 4. Im in one of those Asia country where school uniforms is white shirt. When i buy a new shirt, i notice that the old shirt look white but have blue tint to it. I have no idea why would a dirty old cloth look blue. Then i found out that the cloth washing powder added some small blue dye to it so that it counter the yellow tint of dirty old cloth.
Still recommended for nurse white uniforms actually
this is what we need, people fighting scam ads.
You just have to be moron to ever believe that was real 😂😂
While unfortunately introducing new ones. Perfectly balanced
We are LITERALLY becoming idiocracy.. Ever watched that movie? .. If not, watch it, it's a comedy but it's not funny that it's happening.... We are at early stages.... Idiots creating other idiots creating more idiots
@adrianbik3366 the microcurrent thing is legit, no?
Yeah that was an unfortunate choice for a science channel
Even better than just adding blue is using optical brighteners, which absorb uv light and re-emit it as blue, so it's not just white but BRIGHT white. Laundry detergent, paper, and old carpet cleaning products use these all the time.
Toilet paper glows in the dark
@The Action Lab forgot to set the yellow subtract filter in Adobe Premier
That's cool knowledge, never knew it, thanks
I think it was the old Downy commercials that would actually say, "with bluing for extra whitening".
I'm so glad you did this video! It didn't seem possible, but I figured if anyone would do a great job explaining the science behind it, it would be you. ❤
All I seen was a commercial for skin care. On top of another video explaining light spectrum again
Yes we need more people exposing the fraudulent lies too many people are fooled by. It’s like those 10,000 lumen $15 Chinese flashlights on Amazon have also been proven fake. It helps prevent at least some people from wasting their money. It’s unfortunate the FDA and FTC are not better funded to go after more of the fraudsters.
The other problem is even *if* it worked, it would require that it be staining your teeth with a purple in order to actually counter the yellow staining that is there. Simply putting purple on your teeth then washing it away would defeat all the purple in the first place

the toothpaste is good, But the v34 color corrected is fake
@@HamsterbudsFunny thing is that it’s NOT tooth paste. They make it very clear on the bottle and their website that it is not suppose to be used as a substitute for toothpaste. In other words… ITS USELESS
you literally just made me understand color theory better then then other artist on this platform
trucking true
You were so impressed that you actually stuttered lol how???
@@TOOKSTAH AINT NO FUCKING WAY 🤣🤣🤣🤣🤣
Im sure oridays has one, the guy is awesome and so are his tutorials/guides

Everything you said was spot on. I painted cars for 15 years. An easy way of reducing the chroma or "saturation" of a certain color tone it's by adding the apposing color on the color wheel. And to make a white look cleaner a blue or purple is an easy way to do so.
ok... now I'm going to need a debunk video on your sponsor's anti-wrinkle claims... 😉
Was thinking the same. :D
What's actually wrong with the process; why does it not work? I can think of one possible reason, but it's kind-of iffy in itself: the signs of aging happen because cells lose track of what they're supposed to be. Where it gets iffy is the question of whether the immune system will attack a cell which isn't what it's supposed to be, or whether it'll just assume it's meant to be what it's become.
I'd love to see your research debunking his information on skin tissue repair
Brave man, putting that stuff on your teeth, your sacrifices for science! Thank you so much for helping me learn. Yes please do the additive / subtractive color video
When my daughter was 4, she got a stuffed animal that was yellow. When she brought it to sleep, she freaked out because it had turned black under her dimmed purple night light
is it just lighting? that sounds unfortunate
@@vincentdreemurryes, it's just lighting.
Yellow light has a wavelength of around 570-580nm.
Purple is around 380-400nm.
For an object to appear a certain color, it must absorb most frequencies of light OTHER than the frequencies associated to the color that object appears as. The frequency of light that the object appears as is reflected instead of absorbed.
So if the purple night light is monochromatic (only emitting a single frequency of light) than anything that does not reflect purple light would instead absorb it and appear black.
@@darkdragon1194yeah, I discovered how some things look different under different light colors when I got LED smart lights. LEDs emit narrow and specific wave lengths, making color mixing effects more dramatic
Today, I learned that night lights for children should probably not be saturated colours. But I know I'll forget if I ever have a kid, and any kid of mine will probably be freaked out by this. ^.^;
wow! The Action Lab is just so interesting to watch plus i get some extra knowledge from him. Thank you The Action Lab!
That ad has kept coming up in my feed and I wondered if it was BS. Thank you for clearing that up 🙏🏼
Next, let's debunk the electric skincare device and read an ad for purple toothpaste 😘
Your ease of explaining things turns me green with envy!
This is such a great lesson for a color theory class
I'm currently studying IT and have recently done some learning on printers and monitors and I didn't realise how in dept colour theory was. I'm glad you also covered this in this video.
Oh man, if you’re learning about that in the context of monitors and printers, you haven’t even dipped your toe into the ocean yet. It’s nightmarishly complicated! Next you’ll start learning about CMYK in addition to RGB, then the kelvin color temperature scale, color rendering index or CRI, Adobe, Pantone, and a whole host of other things just to confuse you even more when it comes to calibrating displays and printers and cameras/photos and graphics. It’s no small miracle that anything actually looks like it should, and that colors match as intended - there are a lot of geniuses out there who’ve worked very hard for over a century to make all of that work so well that nobody outside of those industries even thinks about it anymore.
Actually one of the coolest things about it is how much of that has come from artists rather than scientists. Ultimately it’s science that’s made it work right, but they got a huge head start because of the work of a handful of highly influential artists over the last several centuries. There’s some pretty great videos on CZcams by some artists who go over light and color theory in terms of painting and drawing - very _very_ counterintuitive and remarkably awesome to learn!
Hey, so am I.
Color theory also bleeds into psychology. It was used extensively in Breaking Bad to show each character's emotional state in the particular shot. Rewatch knowing this (and the stuff above re: RGB / CMYK) and it changes how you see the show....and everything, lol.
In india,we use a commodity called ujala,which is actually a purple liquid,in this,we dip our washed white shirts to make it look more brighter__thanks for letting us know the science behind this✌️🙃
Debunking a non scientific beauty product while simultaneously selling a non scientific beauty product
😂😂😂
one has research lol
I imagined the tooth paste working like hair toner, which I know from experience really does make orange-yellow hair more of a platinum blond
Same. However, we do know that follow up with the magic shampoo or else it fades back to yellow/orange eventually. So maybe people will have to use too much like they often do with the magic shampoo.
i thought it was straight up just coloured acid
Thank you so much for this video and videos like them. So many people fall prey to these advertisements and hopefully this video will save some folks a few dollars. Now, I know you didn't outright say the product is bogus, and instead hedged your bets...for exactly the same reason they can get away with advertising this stuff: it's totally subjective! Anyway, thanks again!
p.s. I've enjoyed your shots for quite a while now, and this video won me over to finally subscribe! Keep up the good work!
The purple shampoo is designed to make your hair less BRASSY. It tones out yellow or brassy highlights and makes them darker. Brassy highlights are unwanted.
Learning red, blue and yellow are not the primary colors in subtractive coloring was thanks to some CZcams vids. Most of the time, don’t believe what you see and read online, but when I tried mixing yellow and magenta at home to see for myself, I was amazed to see a beautiful bright red staring back at me. Don’t get me started on how magenta and blue make a much more vibrant purple than any red and blue combination ever did. Purple is my favorite color so that’s a big deal for me.
Awesome video, maybe it could have been measured by taking the rgb values from an area of the teeth applying the product in one side and traditional tootpaste in the other? I mean using the color theory as an argument to "whiten" the teeth seems sketchy, but some actual nerdy measurements would have been interesting.
Also, what other properties does it have? Like fluor, something abrasive, alcohol or is it just some type of pigment?
Love to see it when you apply the scientific method in your videos.

he has no clue what he's talking about. Subtractive mixing is well understood science. RYB primaries art teachers talk about are just wrong and obsolete.
@GigsVT lol
Let me debunk a BS product while selling another
First part of your video comes really close to a color perception video I wish you'd do. One that explains the white/gold or blue/black dress. Your brain constantly does an auto white balance (adjustment for the color of the light) based on the expected color of what it sees. It transforms your color perception to match what color it thinks the light is. If a scene or photo lacks sufficient lightning cues, it's possible to get two people to simultaneously see completely different colors. In the dress picture, those who assume the light is white see the dress as white/gold. Those who notice the tiny bit of background in the photo see it is yellow and overexposed. Their brain assumes the light is bright yellow, and they see the dress as blue/black.
What of those folks who saw the dress as baby blue & muddy brown - the actual colors of the pixels themselves?
@@cybisz2883*raises hand* Me too!
They ignored the background
Or zoomed in very closely
Need more videos on color theory please!
This is great i was thinking about this the otber day when I saw that ad. Glad u made this video
This man with his content 💐💐
Thanks for this, those ads have been bugging me for the same reason
here's the trick for when i'm painting with purple and yellow. shadows are naturally blurry, so i always paint shadows with lazy rules, and if you put dark purple in a dark shadow, near a bright yellow or orange, it just looks prettier and you can hide the purple easily. feels better
edit: they use that purple stuff in hair products to make it all glistenny and shiny as well
This is something we do in photo editing to change the white balance.
Photos shot with a cheap light setup at a lower temperature can be made to look natural by varying the color tint.
Hey, badass for backing up your ad read with citations
In your subtractive color video, get some Dioxazine violet (Winsor Violet) and Phthalocyanine green (Winsor Green Blue Shade) from Winsor and Newton and mix them. You will get a blue shade.
Man that video was bananas
Though not used as much, "bluing" is still around for laundry. As you alluded to, it also used to be used in older women's hair which was white. Hence, "blue hair" is slang for and old lady.
Cool video. Been seeing those ads too and thought they were bogus too.
Yep...learned me up a few things. Much obliged.
Tq for all the knowledge 🙂👍
Unbelievable videos. Subscribed. Thank you.
I'd love to learn about the issues with subtractive colour mixing. I've long noticed that useful colour wheels differ from the simple hue circle easily generated with RGB, but I don't know why.
They were using indigo and the cobalt-blue smalt to whiten clothes in the 18th century. Indigo was harder to use, but that's not anything to do with the color difference. It's because indigo as a physical substance is a dye; it can permanently change the clothes color if you're not careful. Smalt is just very finely ground cobalt glass.
Purple shampoo? Maybe it's a regional difference or maybe things have changed over time. All the old books I grew up with called it "blue rinse". This was also the name on the very rare occasions such secrets of the well-kept mature woman were mentioned around small boys. ;)
He messed up additive and subtractive colors. Subtractive is the cyan yellow magenta, additive is RGB
Thank you and both systems use the same color wheel. Red, blue, and yellow being primary colors is a very prominent color theory myth.@@donotreply8979
the main reason purple and yellow are complimentary colors is because purple is the combination of red and blue, all complimentary colors mixing involve one color that is a mixture of the primary, so when you mix in the leftover primary, you'll get black.
however the best way to darken yellow isnt the use a complimentary, but is to mix in a blue bias brown like burnt umber... that is because yellow object dont produce black shadow, they product dark brown shadow that just look black to our eyes...
Pretty sure my kids and I stood in line right in front of your family at Lagoon yesterday. I was going to ask if you were that CZcamsr guy (I couldn’t remember your channel name at the moment).
Hope your family had a good time. My son would’ve love to get a pic with you but I didn’t want to bother your fam and now my 10 year old son is disappointed. Keep on making awesome videos!
Good on you showing em up
Thank you for doing this. I knew it was fake but still wanted to see the science.
Thank you... this is great
Another application is in manufacturing and art, adding a hint of blue dye to slightly-yellow plastics or resin can neutralize the yellow look. That said, it does NOT make the plastic or resin look white, it makes it look GRAY.
I love watching you. I could watch you all day. 🎉 i love learning new stuff.
I believe the video you showed was more about polarized light rather than its pigment, you can get things to look purple or yellow with just a few polarizers.
Love your enquiring mind.
I was planning to buy this product. Thanks for saving me from wasting my money.
Such a great explaination of what should be obvious, but clearly isn't to so many
Wow thank you for the informative video
I'm glad someone finally addressed this. As someone who knows color theory I've been seeing those ads and screaming; "THATS NOT HOW COLOR WORKS!!!" at my phone.
I use a whitening shampoo on my Komondors and it really brightens them up. It is dark blue to start out with. I is very noticeable after i use it. I didn't know it was just hiding the yellow.
i like your channel very informational.
Are we getting ads from another universe with different physics rules?
I'd love to see a more in-depth color theory video!
Ur doing gods work sir
I remember the dentists flouride treatment at the end of my appointment was always purple when i was a kid.
Video on color mixing please
I just got this ad and considered buying it, thanks for the debunk
I used to do experiments with colours in school
... I miss those days!
Wait. The purple doesn’t work for color but the electric shock device works for skin wrinkles? Is this April 1?
I just learned about color theory!!! And I used that website!!!
Subtractive coloring is definitely a must watch
Lmao
Amazing your videos are great
2:34 Love that magical changing shirt.
you need to do a video on a farnsworth fusor reactor
sometimes the epoxy resin that crafters and woodturners use can yellow over time so people add purple or blue dye to it when mixing to neutralize the yellowing that occurs.
I've been watching you for a few years. Great video!
Which color combination makes a mirror color? and does it reflect?
Good work 👍
I’ve seen these hismile ads 20 million times. It’s obviously nonsense. I’m so glad you made this video. You were far more polite than I would have been lol
try with 2 lights(yellow and purple), may be it can work
Pls make a video on colour theory and how a person on youtube is able to make any coulour they want
This is like those videos that show you can make a B&W image have colour by adding a Red, Green and Blue filter atop of it
Bringing me back to middle school art class
Great video! Now do something similar for the skin gadget that you're selling
Thank you so much for this. I knew they were lying I just couldn’t explain it. 😅
Still one of the most helpful scientists out there
Wish you good health.
It doesn't matter whether you use additive or subtractive colors. Complements are the same. Either yellow is a mix of red and green and the compliment is blue, or yellow is a primary color and the complements are magenta and cyan, which mix to blue. The only way you get purple is if you make the primary colors red yellow and blue, and that's not right for additive or subtractive colors. But they teach it in school for some reason.
5:53 It kinda does, but did you do a control to brush all the teeth first to ensure there was no biofilm/tarter?
White leds use a sulfur lens to make the blue lite to white also
I’ve seen this work with white led strips that have turned yellow. I used a purple marker on them and the light came out white.
How about ceiling paint for your house it goes on purple and dries white? Is this related in anyway to this toothpaste claim.
Sad part is the product actually works, just not in the "blink and you'll miss it" manner portrayed in the ads. I started seeing notable whitening after a week of use. The team responsible for promotions might have singlehandedly ruined this product.
Love the shirt.
Blue to white has been a well known optical illusion for us in developing world. We have old blue detergent for this. Modern detergent no longer do this due to using actual bleach to improve whiteness while also having color bonder to improve color contrast on clothes.
Thank you, pls suggest me topic of theoretical physics for PhD.
This dude is incredible! how could he even know all that stuff
I read that all clear phone case plastic has yellow tinge but they add blue dye to offset the yellow and make it look clear. When the blue fades it looks yellow again. Thats why we think clear phone cases turn yellow over time. But thats not the case since they were always yellow but it was just hidden by blue additive in the plastic.
I cant verify the authenticity of this though.
Best brother.

I seen that add…was thinking hmmm this is a faster way to implants or dentures.
Should try this with glow sticks🧐 it's works a bit different I believe 🤔🤟
Great video - if only to call out the false advertising of purple turning the banana white.
We see a LOT of dodgey claims these days. Even the BEAR device ... is it actually having any impact on the reduction of the wrinkles or is it the "serum" that's doing the magic? And is the "serum" really just moisturising cream?
3 months ago I had really dry, creased skin under my eyes - it almost looked ready to crack. The problem was I was only getting 3-4 hours / night of sleep and was dehydrated. Some simple moisturising cream, drinking more water and giving my body a decent night's sleep (7-8 hours) fixed all of that within about 3 days.
So I'm more than just a bit sceptical about the BEAR device and also whether people really need to spend unnecessary money on a device that's not achieving anything that's not already possible at a fraction of the price. It would be great to see a comparison of two people with similar skin conditions and dermal composition, age, etc., ... trying the BEAR solution vs normal moisturing cream, water and a cold face-roller.
I’m tagging this video in every ad I see…
Printers use the correct subtractive primaries - magenta, cyan and yellow. Magenta is the absence of green light, cyan the absence of red light and yellow the absence of blue light.
