Why There Are No Bluish-Yellow Crayons: The Forbidden Color Experiment

Follow me on:

In this video I see if you can see this forbidden color! I explain what a forbidden color is and then I actually show you that you cannot see it in a real experiment. I talk about why bluish yellow and reddish green is a color that no one can see. Then I show you a way that you may be able to see a new color that you have never before realized. Most people cannot see this color.

2017: orange is the new black.
2018. Yellowish blue is the new White.

It was like a grey made of yellow and blue. Sort of like shading a piece of paper with blue and yellow crayons. They don’t mix into green, and you still see both colors, but they appear muddy.

Doing the cross-eye thing, the best way I could describe it is that it looked like when you put two objects in the exact same space on a 3d modeler and it starts flashing both colors (called z-fighting) but never mixes. it was smoother than normal z-fighting though, it looked like the colors were swirling around each other

[jonathangarlinghouse]

I crossed my eyes and saw a solid color in the mix. I did not get the "flashing" effect, and I did not really see any green, but I saw something like a sea-foam yellow? Pretty cool experiment!

If I start a country, my flag will have this color just to screw with people

"There's no such hue as yellowish blue."
The guy who carves my epitaph is going to be really confused.

[radioactive]

I thought I would see green when I cross my eyes but the color I see is a dirty yellow. Like some sort of yellow with a dark filter.

[geoffschulz]

This is one of my main pet peeves. Artists keep perpetuating the myth that the primary colors are Red, Blue and Yellow. There is a difference between "Active colors" and "Passive colors". The active primary color set (projected light) is Red, Blue and Green. Active colors can be added together to create different colors. Passive colors (reflective surfaces, like paint or ink) absorb colors and can be combined to subtract color. So, the real color wheel for paint and printer ink is Magenta, Cyan and Yellow. I believe that artists from long ago saw Blue as being similar to Cyan and Red as being similar to Magenta and chose them as primaries, being the most common in nature. Mixing Blue and Yellow paint does not produce Green, but mixing Cyan and Yellow does. Mixing Blue and Green light produces Yellow.

RIGHT as I started to move the screen closer to my eyes to try to see yellowish blue, a pest ad with a roach running at me popped up. I was not expecting a jump scare, thank you very much!! 😱

I just love how he can go on a tangent about something nobody wanted to know but are glad they found out

[AnimeOtakuDrew]

I saw a video about this same idea from Kyle Hill a few months back in which he had a similar test, not only to see yellowish blue, but also greenish red, and under the right circumstances I was able to perceive both. I actually find the yellowish blue to be a beautiful color and I wish it could appear as a normal color; I would paint my house that color if I could.

Hes also actually talking about Lab color space. L stands for luminance, where the g and b that he mentioned earlier are a and b respectively. A goes from green to magenta, and B goes from yellow to blue.

[paulfitzgerald]

As a photographer this is the most awesome demonstration of how we have to achieve white balance in Lightroom. Our color temperature is between yellow and blue. Then we have tint which is between Magenta & Green. Now I realize I'm actually trying to get the color to look right to both the cones and the subtractive cells. Great info! :)

[edwardrevin]

Looked more like a gradient between yellow and blue that was constantly morphing direction between the two colors.

[johnperivolaris]

When I cross my eyes I see yellow and blue overtaking each other constantly in a sort of 'colour wave' until they mix briefly, turning into a pale green.

[heckensteiner]

When I crossed my eyes, I saw flashing between yellow and blue. When I relaxed my eyes, I saw a gradient from blue to yellow and sometimes a tiny hint of greenish grey in the middle. The gradient slowly fluctuates from more yellow to more blue, but it still feels like either yellow or blue. Fascinating stuff! This is why I love Action Lab: simple and engaging experiments that explain the more complex concepts behind them. Reminds me of when I used to watch Bill Nye as a kid.

[emero.a.scythe]

I noticed that when two colors are right next to each other like that, with the yellow and blue, I'll see a little bit of different color, and right in the middle of those two, it looked like a weird purpleish color. Like, I'd describe it as like, a white gold, but with a purple-y hue instead of a yellow-y one.
Same thing happened when he was mixing the lights.

[ritparent]

For me, the field would start out Blue with a small Yellow outline of the plus sign. Then they would mix into the Blueish-Yellow Grey. When I would blink, it would revert back to the starting point of mostly Blue with a small amount of Yellow around the plus sign, then mix again. Is anyone NOT seeing this?

[gustavocosta]

I saw the Bluish-Yellow, but there are some people saying that the color they saw is like a purple color, now I'm confused and I don't know which is the correct Bluish-Yellow.

[dankspanx]

I’m colorblind. Why am I watching this?
