Comment on Blue could have been a warmest color
remon@ani.social 6 days agoThe sun is, by definition, white
White light is light that contains all visible wavelengths at the roughly the same proportions. The sun has nothing to do with this definition.
Our sun is actually slightly greenish-blue as that is where it’s peak output is.

The key word there is “visible”. Our eyes adapted to the spectra of our star when filtered by our atmosphere. We perceive that spectra as white.

Our perception is limited and our understanding has long outgrown it. White light, by definition is all visible light at equal intensity, thus the sun is NOT white.
Use RGB codes for example. White, by definition is 255, 255, 255.
The Sun would be more like 245, 253, 255 … still looks white to us, but by definition, isn’t.

Can we agree it’s not orange? That is what I was originally pointing out.

From a physical standpoint, sure.
But I’m pretty sure that if you casually ask most people which colour the sun is, you’ll hear yellow/orange much more often than white. So for the context of which colour was, prehistorically, associated with warmth I think yellow/orange are the more relevant answer.

Actually…
our eyes adapted way back when our ancestors were fish. So we see light in the range that light passes best under water.
