People often explain this by saying that dark colours are good absorbers of radiation (compared to white). But in itself this explanation is not sufficient; a good absorber of radiation is (by definition) also a good emitter of radiation!
Does the dark T shirt enable your body to reach thermal equilibrium with the warm surroundings faster that a white T shirt? If this is the case, then if you're outside for a while (long enough for the white T-shirt to reach thermal equilibrium with its surroundings) wouldn't a white T-shirt be just as warm as a dark T-shirt?
Or is it that a dark T-shirt reaches thermal equilibrium at a higher temperature than a white T-shirt? (If so please explain. This seems to contradict my previous understanding of thermal equilibrium)
