This article was a fascinating and informative read for me.
The author (who I assume is male, I don't remember if he said so outright) kept repeating how colour is perceived based on the difference between receptor signals. I had learned that already so I kept thinking, "yeah yeah, I know"...
... Then he got to the point about edge detection, and suddenly I understood! I never thought before about how the difference is calculated between receptors that are not precisely co-located on the retina. Of course! Seems obvious in retrospect but I never thought about it. That also makes many colour-optical illusions make more sense.
If the author comes across these comments -- I have full colour vision and unusually good eyesight. Even for me, without magnification the stars are not colourful. Mars is slightly red, Betelgeuse is very slightly red, the milky way has a slightly bluish tinge, but for the most part, the stars are just white points. They do sometimes shimmer / twinkle briefly between different colours in a way that can make it really hard to say what exact colour they are, even if I stare at them. You probably notice that too, though. So I don't think your experience of the stars is likely to be that different, and you shouldn't feel sad!
