You do make a good point, the color of a star reflects its peak output, the fact that the star emits a range of light with just the peak defining its color. Our own sun should, by that peak color thinking, be greenish but there are no green stars, the rest of the sun's spectrum washes out the green peaks.
I tried to look this up but no joy, too many pages of the color of stars based on their spectrum on Google but... I saw recently where it is thought that if the Earth was placed around a red star or a blue blue star the color of the star would appear close to what we see from earth due to the peak temp being a peak that ignores the rest of the spectrum. Our own eyes would probably fool us into seeing a moreor less yellow sun in the sky. Evidently googling this requires more finesse than I have.
I would like to see a source for this please, it goes against everything I know about plants and photosynthesis.
