Why do we perceive the sun as yellow? I understand that its colour arises from the mixture of wavelengths in sunlight. But as sunlight has been the main source of illumination throughout evolution 鈥� the background light to everything on the planet up to the invention of electric light 鈥� it gives us our default colour for everything. So why don鈥檛 we consider it to be the neutral colour 鈥� in other words, white?
