What type of heat transfer is affected by color?

Answer 1

Cricketers wear white because white reflects both light and heat. If you wear a black T-shirt on the cricket pitch you will get real hot real quick!

Scientists and Engineers define a Black Body as something that absorbs all the radiation coming toward it.

Photographers define Color Temperature as the temperature of a black body that radiates light of that color.

So there is a link between color and temperature, and there is a link between temperature and heat transfer.

The definitive answer to this question is really complicated, including concepts like radiation, emissivity and the electromagnetic spectrum.

Yes surely colour affects greatly on the amount of absorption and reflection of heat. Black absorbs heat the most and white reflects heat. When a material is coated black its heat absorption potential increases as well. Dark colours have the same effect . No one would possibly have wondered why party wears are dark or mostly black...It sure adds to the shimmer and salient effect for sure but the main reason is that most parties are conducted towards the evening. Parties are common to western culture and in West evenings are cold. Hence wearing a black suite helps you stay warm.

We find more examples to the relation between colour and heat transfer considering materials relate to solar power. Solar cookers and utensils have a black coating on its surface and the box is coated black in the inside to increase the amount of heat absorbed. The black coating helps it absorb more heat in less time allowing the boosting of heat in the cooker.

Answer 2

Radiation!!
