The color circle can be divided into warm and cool colors.
Warm colors are vivid and energetic, and tend to advance in space.
Cool colors give an impression of calm, and create a soothing impression.
White, black and gray are considered to be neutral.These terms are often used incorrectly, although they describe fairly simple color concepts. If a color is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. And if gray is added, the result is a different tone.
