Extended data:

Refers to the difference between cool color and warm color. According to psychological feelings, colors are divided into warm colors (red and orange), cool colors (green and blue) and neutral colors (purple, yellow, black, gray and white). In painting and design, warm colors give people a sense of intimacy and warmth; Cool colors give people a sense of distance and coolness. Complex colors depend on their specific composition and appearance.

Red and orange are often associated with red flames, so they have a warm feeling, so they are called "warm colors"; Green and blue are often associated with green forests and blue ice and snow, so they feel cold, so they are called "cool colors"; Colors such as yellow and purple give people the impression that they are neither hot nor cold, so they are called "neutral colors".

Cold and warm colors are relative. For the same color, more warm colors are warmer, and vice versa.
