There are many Tritanopia CVD simulations out there. But I read many times in this subreddit that people with Red-Green CVD see mostly black/white/greyscale in these simulations. The reason is that the Blue-Yellow CVD color palet feature mostly colors that people with Red-Green CVD struggle with. But make no mistake, Blue-Yellow CVD is just as colorfol as Red-Green CVD.

For this reason, I designed a Tritanopia CVD simulation that uses a color palet that is accessible to people with Red-Green CVD, giving Protans and Deutans a better understanding of how Tritanopes see the world.

In my previous post I created a picture of all colors that a dichromat can see. https://www.reddit.com/r/ColorBlind/comments/1sun5gs/every_color_that_a_dichromat_can_see/

There someone got curious about all colors that a trichromat can see, so I got creative and created a video that scrolls through all trichromatic colors.

Here's a picture of every color that a dichromat can perceive. A dichromat can only see two distinct hues and every color they can perceive are just variations in saturation and brightness. Whereas a trichromat can see a range, a full dimension of hues, instead of just two distinct hues.

dichromat color space (totalred-green blindness)

If a dichromat (total red-green blindness) looks at the given picture, they see all the colors and can't point out one that is clearly missing.

If a normal trichromat sees this picture, they see just about 1% of the colors. There's yellow, but every shade from orange to red to pink to purple to indigo is missing. Then there's blue, but every shade from cyan to green to lime is missing.

Of course, most people with a color vision deficiency are anomalous trichomats. They can spot that the more saturated greens, reds, etc. are absent in the picture, but they can't see most of the 99% of colors that are missing in the picture.

Here's the picture with total blue-yellow blindness, featuring only cyan and red hue.
