The poster's question should be interpreted as: can the color of the stars be distinguished with the naked eye?

[grzm]

Again, yes. Particularly in clusters, I can detect differences in the colors of stars.

Wow - sounds like you have more sensitive than average color perception.

Do you think you might be a tetrachromat?

[grzm]

Nope. It probably helps to live away from cities and such, in that there's a lot of stars visible at night. And it's not like looking at a rainbow: they're tints, not intense color differences.

'endogui linked to an article that talks about this: I don't think it's all that unusual.
