I Question about the absorption of heat based on color

[timeuser84]

Hello there all, long time. I am not sure where to ask this question so If I am in the wrong area of forum, I ask that the moderator or administrator move this thread to the correct one please.

Is it true that any clothes you wear depending on the color will absorb heat because its black? For example if you wear black socks, will the black socks absorb heat more because its black or a dark color?

Direct sunlight will tend to warm up dark clothes more than light colored clothes.

Three different parts of the spectrum need to be considered.
1. Ultraviolet, UV.
2. Visible light colour.
3. Infrared, heat, IR.

The colour of clothing you see, is the colour of the visible light that is reflected from the clothing. Visible light that is not reflected becomes heat in the cloth. Some of that is radiated, while some will warm the wearer.

The reflectivity of the cloth to IR and UV cannot be seen by our eyes, but any IR or UV absorbed, will also heat the cloth.

Black clothing will absorb visible light better, but black may also radiate IR better. Material thickness will act as an insulator between your body and the environment. At night, you may want to stay warm.
