Of all colors in the spectrum, why is snow white?

here, do this experiment:

shine yellow light on snow. what does it look like?

shine ultraviolet light on snow. what does it look like?

cells in human eyes are differentially sensitive to different wavelengths, but all the light we can see is still in a very narrow band.

snow is white, to us, because it is diffusely reflective in the visible wavelengths.

oh, and by the way yes, you do get rainbow effects. take some photos of freshly fallen snow on a sunny day, with a macro lens.. especially if the flakes are large

Because purple snow would look weird. Just think of black snow. It's just..... no.

- You wouldnt want yellow snow either. What are the heavens peeing on us now?

- Pink snow wouldnt be too bad, but it would still look weird

- Green snow would look like overgrown and cold grass

- Brown snow..... no

- Red snow.. World war III already started?

~Blue snow would look the best. Kind of like a cerulean or sky blue color, but white snow just sounds the best to me :)
