FWIW when we say "a light at 6000 K" it means "a light with the same color as a black body heated to 6000 Kelvin", so it has nothing to do with temperature, it's only a (veery rough) way of characterizing color.

The sun indeed qualifies as a black body (I know, it's pretty bright... but black body just means it doesn't reflect light coming from somewhere else)
