Comment on The sun is a deadly laser...

It probably would never appear green, due to the black-body radiation distribution. When the peak is at green, it just looks like white to us. Our sun is kinda a “green” star due to this
But it would go from blue to white to red. Similar colour progression that we can find in the distribution of stars

Indeed! Good point! For some reason, I was under the impression that the CMB was monochromatic (corresponding to a red shifted equivalent of the precise energy of W and Z boson annihilation). Thanks!!
