After re-reading that link I just posted, It sounds kinda contradictive? Heres a little extract out of an article in a book I have..
Viewed by an eye not subjected to other strong
lights, and with very little other light sources in the
field of view, will virtually never look green. But put the same
star (which we can assume to appear white when viewed in isolation)
close to another reddish star and that same star may immediately
look greenish, due to contrast effects (the eye tries to make the
"average" color of the two stars appear white).
That seems to sum up Antares to a tee.
