The radiation curve of the sun shows that the brightest light from the sun is a yellow-green. So then why do we see the sun as whitish instead of yellow-green?

Although the irradiance is greater in the region of 500 nm, this is not the only wavelength. The mixture of the entire band from 300 to over 1000 nm is sufficient to trigger the cones in the human eye to "see" all of the colors of the visible spectrum and the brain interprets this as "white light."

Most peoples eyes are most sensitive to the green too at low light levels, the thing is that when you look even near the sun just for a moment just about every sensor in your eyes overloads - any really bright light will look whiter than it really is which is why we can get away with using tunsten filament lamps (it's a very yellowy orange light but if it's bright enough your eyes and brain adapt to see it as nearly white).

The nitrogen in our atmosphere filters out much of the green light given off by the sun leaving a yellow white appearance.

The blue part of the spectrum of the solar's easy is filtered by our ecosystem and is scattered, making the sky blue. The solar seems extra in the direction of the purple end of its ordinary shade to us in the international. the quantity of green easy in the spectrum is plenty smaller than the others. Evolution has made our eyes extra gentle to the fairway, as an help in looking suitable for eating plant life.
