Because it has no color, therefore nothing to absorb. With light energy, surface colors absorb and reflect various color frequencies (electro-magnetic wavelengths). For instance, blue paint reflects higher frequency wavelengths which our eyes see, and our brains interpret, as blue values, and it absorbs lower range frequencies we would interpret as red and yellow. White surfaces reflect high quantities of all of the visible range of frequencies of electro-magnetic wavelengths, so the frequencies reflected back at the viewer contain all visible color ranges that are contained in the light hitting that surface and appear the same color.
The color white reflects light. The color black absorbs light. The other colors reflect the wavelenghts of light that correspond to the color. Since white reflects light and does not absorb it, it reflects infrared, and ultraviolet, the wavelenghts of light typically referred to as heat. It is not absolute, as there is only one true white, but many very close colors that are indistinguishable from white to the naked eye, but may not reflect ultraviolet, the main source of heat from our sun. In short, yes. A white object will be cooler than a black one.
Shiny white surfaces are good heat reflectors , but bad heat emitters or absorbers .
Dull black surfaces are bad heat reflectors , but good heat emitters and absorbers
AnswerIt is not exactly a case of reflecting or absorbing "heat". An object appears white if it reflects light. If an object absorbs light, the energy of the light is converted into heat energy within the object. Therefore, a white object will absorb less radiation and therefore will heat up less when exposed to light. Note that a this only applies for heat transfer via radiation. The colour will have no effect on the amount of heat transferred by direct conduction. .Longer than black, if that's what you're asking - black objects are the best radiators.
The color black.

If you are asking do certain colours absorb or reflect heat more then the answer is yes. Black absorbs heat at a far greater rate than white. White is used to reflect heat.
Tricky question. If the surfaces are the same, then silver will absorb more, but in the case of a silver mirror, it will reflect more light, so the white will absorb more. Save
White and light colors reflect heat. Black & dark colors absorb heat.
Darker materials tend to absorb solar heat, while lighter materials reflect it.

White. Dark colours absorb heat, light colours reflect the heat.

I believe its because of the color, since sand can be a brownish color, the color would absorb the heat from the sun. BUT, if the color was light, like white, it wouldn't absorb as much heat.
the reason is all light colors for example white, yellow don't absorb light they just reflect it, but dark colors absorb it the light and black being the darkest color absorbs the must heat and light.
Reflect
Because black has almost no ability to reflect heat. White reflects heat very well, black hardly at all, so the heat builds up in black.
Light colours. White is best.
