Various cultures see color differently. In India, blue is associated with Krishna (a very positive association), green with Islam, red with purity (used as a wedding colour) and white with mourning. In most Asian cultures, yellow is the imperial color with many of the same cultural associations as purple in the west. In China, red is symbolic of celebration, luck and prosperity; white is symbolic of mourning and death, while "having a green hat" metaphorically means a man’s wife is cheating on him. In Europe colors are more strongly associated with political parties than they are in the U.S. In many countries black is synonymous with conservatism, red with socialism, while brown is still immediately associated with the Nazis. Many believe that blue is universally the best color as it has the most positive and fewest negative cultural associations across various cultures. The symbolism of color can also be seen in localised religious divisions, in the UK for example, cities such as Liverpool (England), Glasgow (Scotland) and Belfast (Northern Ireland) where Catholic and Protestant have a history of conflict, the use green (Catholicism) or Orange (Protestantism) are seen as almost taboo by opposing socioreligious groups.

Colors, especially the natural colors are frequently associated with seasons and geographical cardinal directions, although the specific assignments vary widely among individual cultures.
