It's a little funny we can explain an "Einstein iron cross" as four views of a galaxy 8 billion light years away but the color of a star 8 light minutes away ...well that's another matter.
There was an interesting article on this in Astronomy earlier this year. The author, as I recall, claimed the sun was greenish (outside our atmosphere). If you want, I'll dig it up.
The atmosphere must play a crticial role in the color we perceive as it is white at noon, then yellow, orange and redish.
The sun appears to me to peak around 450 nm - Blue. Here, I hope, is the Sun's light curve >>>

Others say it is more the sumation of all the wavelengths that gives the final color appearance. This, of course, is tied to our eye's reception. BTW thanks for that link Visitor.
Since the Sun is so bright in space, it is not seen as anything other than white as far as I know. Color cones are overmodulated with the Suns light. (Not the best word to describe it but I just like saying it.)
There ought to be some way to take solar data, lower the intesity so the color cones are not flooded (overmodulated) and "see" how it looks. Or how about a distant satelite near Jupiter taking a quick look in the visual spectrum....oops too late. But, maybe Galileo did. Anyone know?
