Usage, symbolism, colloquial expressions
In Western societies black is most often used with a negative connotation, with a few notable exceptions. For instance, a "black day" would be used in these cultures to refer to a sad or tragic day. However, to say one's accounts are "in the black" is used to mean that one is free of debt (a very positive thing in a capitalist society).
In arguments things can be black or white, or shades of gray, the intensity used as an analogue for things such as truthfulness or right and wrong. (Note that when referring to the intensity of pigment or light, black is always the complete lack of intensity.)
In Western cultures and their colonial offshoots, the color black is often used in painting, film, and literature to evoke a sense of the unknown or of death. In these cultures, the color black is often seen as the color of mourning, though this convention is less strict than in earlier times, when widows and widowers were expected to wear black for a year after the death of their spouses.
However, in other cultures, such as the Maasai tribes of Kenya and Tanzania, the color black is associated with rain clouds and is thus a symbol of life and prosperity
