The star could be hotter than that, thus she could appear white or even blue maybe but I'm not sure it's possible to differentiate the color even with basic observation tools. It's more about radiations and for that you need much more advanced equipment. Anyway, if someone have the luxury to stare at the Sun long enough to figure what color it... become black

Light has no color in nature so does the stars I think. I'm not sure : File:Sirius A and B artwork.jpg - Wikipedia, the free encyclopedia But I prefer when they have colors
oh and the star would be about the size of Venus
