Understand similar colors, adjacent colors, contrasting colors and complementary colors.

Homologous color: 30 degrees on both sides of its own color is called homozygous color.

Generally, they are similar hues, and the diversity of picture colors is expressed by lightness and saturation.

Similar colors are similar in hue, so the pictures presented by similar color matching works are generally harmonious; However, due to the single color, the picture is not expressive enough, monotonous and lacks a sense of hierarchy.

Adjacent color: the color of 60 degrees on both sides of its own color is called adjacent color.

Adjacent colors in the color phase ring are called adjacent colors.

Adjacent colors are similar in nature, because their positions in the color circle are very close. Therefore, the picture effect of the color matching works with adjacent colors is generally harmonious, but the adjacent colors have more hues than the similar colors, so the picture effect is brighter and there is a certain color contrast. The disadvantage is that the color performance of the picture is not rich enough.

Contrast color: 120 degrees. The color of both sides is called contrast color.

Contrast color is a color with strong color contrast, so it is generally used in works with strong visual impact to highlight the theme. Because of the strong contrast, it is generally not used in equal proportion. To use equal proportions, reeds must be balanced with other colors.

Complementary color: It is called complementary color if it forms 180 degrees with its own color.

Complementary color is the color with the strongest contrast among colors, and its visual impact is stronger than that of contrast color, which is eye-catching, generally manifested in works such as strength, hard work, excitement and enthusiasm. However, because the contrast is too strong, achromatic black, white and gray are often used to neutralize the picture, which makes the picture more harmonious.
