The reflection of blue light will impart blue color to the shirt as it reaches our eyes. Understand that the difference between a black and white shirt is that the black shirt has a greater absorbance and hence a greater emissivity(objects that absorb most also emit the most heat by radiation, as emissivity is equal to absorbance by Kirchhoff's laws).

The earth is affected in the same way. Science isn't always about the big questions. The more light a color absorbs, the more thermal energy it produces. Black objects can radiate energy (heat) as good as they can absorb it. If you mean protection from UV, then the colour of the clothes makes no difference. Dark colors become hotter in sun light than light colors for a reason that dark colors absorb more light. My manager (with a history of reneging on bonuses) is offering a future bonus to make me stay. Please, please, please help!

Why do Bedouins wear black robes when everyone knows that black is a strong heat absorber? Now, whether it's absorbed or not will depend on the structure of the electrons [in the atom]. Dark colours do not exactly absorb more heat, but they do convert a higher percentage of light into heat. After measuring the temperatures of the water, the glass with the black paper around it should be hotter than the other. What Happens If You Wear Black In The Sun? , Dr. Howard Fields, No Comment, January 1, 2018 Have you ever noticed that summer clothes are usually made of lighter colored fabrics?
