Most of sunlight is in the visible range of the spectrum. A black object by definition absorbs all visible light, while a white object reflects all visible light. The black object absorbs most of the energy from sunlight, turning it into heat.
Objects can either emit light and heat of their own, or they can reflect light and heat from other sources such as the Sun. Most objects (except light bulbs) do not emit light of their own; they only reflect the light that hits them. The COLOR of an object is determined by which colors of light it reflects; red objects reflect primarily red light, while blue objects reflect more blue light. White objects reflect all colors, while black objects don't reflect any colors very well.
Which is why a black object gets warmer in the sunlight than other colors do; the black object reflects very little of the sunlight that hits it, and instead absorbs the light energy. Where does the absorbed light go? Noplace; it becomes heat and is retained within the object. So black clothing helps you to absorb heat on a cool day.
That's why, if you look at photos of hot air balloons, the very top of the balloon is often black; to absorb solar energy from the Sun, and transfer it into the balloon which will heat up the air within. Black balloons absorb enough heat from the Sun to save several percent in fuel costs!
Black objects absorb radiation whereas white ones reflect it.
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
White surfaces reflects light - black absorbs it
Light is really all the colors of the rainbow for example if and object is blue it absorbs all colors except blue so a white object would look white because it REFLECTS all the colors of the rainbow a black object looks black because it ABSORBS all the colors
because black atracts the heat wear as white reflects it! :)

a white shirt is cooler in the summer time

yes
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
Colour is basically how much sunlight the object absorbs/reflects. Black absorbs all sunlight which is why it is so dark, white reflects all sunlight which is why it is so bright. So if the ice cube is say black, it will melt faster than if an ice cube was white, because of how much sunlight is absorbed.
Because white reflects sunlight, and black absorbs sunlight. Therefore, a white car would be cooler.
Sunlight cannot turn black into white. However, a black surface may appear white in bright sunlight due to reflection of all the wavelengths of light from a shiny surface. The color black is actually the result of the absence of reflection of any wavelengths of light while the color white is the result of reflection of all the wavelengths of light.
The black one would be.
White reflects sunlight (energy) back into space.
Yes. A white shirt reflects more sunlight than a black one which absorbs it. Absorbed sunlight is converted into heat.
