The Sun is Green

Literally!
The Sun is a pretty good blackbody at 5500K and, via the Wein Displacement Law, peaks around 5000 Angstroms, just about the color green. This has 2 consequences in your normal life:

1) your eye has evolved to take advantage of this. You are twice as sensitive to green photons as red and are most sensitive to the peak of the Sun's light, well into the green.*

2) its why plants are green.

When I was teaching Astronomy or doing shows at Buhl Planetarium in Pittsburgh, I used to do a show called "Life under Other Stars" exploring this phenomenon and speculating what the world would look like of the Sun were hotter (bluer) or cooler (redder).

I used colored lights and a metric shitload of speculation (not being trained as an astrobiologist).

Here, it's done right!

*so why doesn't the sun look green? You eye is a fairly narrow band, integration bolometer. While there is a peak in the BB radiation curve at the solar peak, compared to your eye's narrow bandwidth, that peak seems relatively flat, e.g. there are 1000 red photons, 1500 green photons and 1000 blue photons at the peak within your bandwidth (approximately). You eye and brain integrate across the whole bandwidth and make the sun look white.
