>>13194390Color is in fact a hard-coded illusion created by the brain, it is a survival function to help animals tell different objects apart. What i mean by illusion is that there is no such thing as "red", not objectively. Other animals, especially those quite far away on the evolutionary tree from us, very likely see different colors entirely given a wavelength that we would call red. Colors we literally cannot imagine, and they are unable to imagine our colors too.
So while REDNESS is subjective and in fact fictional, there is still objective wavelengths to the light. The light wavelengths exist, but the color you interpret those wavelengths to look like depends on what animal you are and is sorta fundamentally not fully understandable by humans. It is similar to temperature--there is no such thing as "cold", just heat energy and less heat energy. But we feel the sensations of cold and hot to be completely opposite for survival purposes and because our bodies do not, cannot, measure things objectively but rather how things compare relative to itself.
Also the sun is white, it only looks yellow when viewed through our blue atmosphere. Here's a pic from a satellite with very little atmosphere to filter through. In retrospect it would make sense that it is white, because it contains all colors, because its light is literally the thing we evolved to see all colors from. I know it sounds like a conspiracy but NASA does in fact artificially color their spqce-taken photographs of the sun to be yellow-orange. It is necessary to colorize these photographs because of the methods used to take them, and they choose yellow-orangw because that's what people expect, but the sun is pure white. The purest white, in fact.
