::Or maybe it's photos like we see here: White dwarf#Radiation and cooling. It seems to me we've entered into another of those physics-related "misconceptions" where the kind of exact terminology that's necessary in one specific field is inapplicable to everyday life. At the very least, we should say something like, "the terminology astronomers have frequently used for dwarf stars, yellow dwarf (such as our Sun), blue dwarf, red dwarf, etc, is misleading to the public, and the colors do not match physicists' definition of color."It's a non-sequitur to suggest that the perception of color is in error compared with something called "true" color. There is no objective definition of red or green or white. It's a combination of our biology and psychology that creates the concepts of color in the first place, arbitrarily eliminating some colors, like ultraviolet and infrared, while giving names to colors as we perceive them.
