I recently saw an example of red-green blindness and I cannot wrap my head around how they’re able to see both yellow and blue vividly. If they can see yellow and blue individually, why can they not see green?
I did a bit of searching and learned how the red, green, and blue cones in your eyes work, so I was temporarily satisfied that it was the same as TVs and monitors that don’t actually produce the colour yellow but only give the illusion… Until I remembered that the illusion is achieved by combining red and green light, so wtf.
Help my brain. Make it simple.

Don’t think of it in terms of being able to “see” the colours, but rather in being able to tell them apart. People with RG colourblindness can tell yellow apart from blue because they can differentiate the presence/absence of blue light, but can’t tell you if it’s a greenish yellow or reddish yellow.
