Black
In light, black is lack of all color. In painting, however, the black pigment is the combination of all colors. In heraldry, black is called "sable". It is the opposite of white.

Origin of black
The word "black" comes from Old English blæc ("black, dark", also, "ink"), from Proto-Germanic *blakkaz ("burned"), and from Proto-Indo-European *bhleg-. Black is the darkest color/tone on a scale.
Black in science
In science, an object that is black absorbs the light that hits it. Because these objects do not reflect any light, the human eye can't see any color coming from that object. The brain then sees these objects as black.
A way to create black objects is to mix pigments. A pigment works by reflecting only the color of the pigment. For example, a blue pigment absorbs all colors except blue. By mixing pigments in the right quantities, black can be made.
In sunlight, black objects become quickly warm because they absorb much light.
