The poster's question should be interpreted as: can the color of the stars be distinguished with the naked eye?
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?
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.
> "The color of a star, as determined by the most intense frequency of the visible light, depends on the temperature of the star's outer layers, including its photosphere."
