Adjacent colors, two colors separated by 60 degrees or three digits in the color circle, are adjacent colors and belong to the color group with medium contrast effect. The hue is similar, the cold and warm properties are consistent, the hue is unified and harmonious, and the emotional characteristics are consistent. Such as red and yellow-green, blue and yellow-green.
Similar color, similar color is similar color. Adjacent colors within 90 degrees of the color wheel are collectively referred to as similar colors, such as red-red orange-orange, yellow-yellow-green-green, cyan-cyan-purple and so on.
Medium-difference color, 2-3 colors from this hue are similar colors, and 4-7 colors from this hue are medium-difference colors.
Contrast color refers to two colors on the 24-color ring that are between 120 degrees and 180 degrees apart, which is called contrast color.
Extended data
The characteristics of hue depend on the spectral composition of light source and the perception of human eyes caused by the proportion of radiation with various wavelengths reflected from the surface of colored objects. When measuring color, it can be expressed by hue angle h and main wavelength λd(nm).
In polymer, it is the color sense corresponding to the main wavelength and complementary main wavelength expressed according to XZY series colors. Generally, compared with the standard color solution in molten state, the consistent color scale is called hue number. Because there are many kinds of polymers, there are many standard color systems. The commonly used standard color systems are all prepared in accordance with the methods specified in national standards.
The relative color of each color (diagonal 180) in the color phase ring is called complementary color, which is also the color group with the strongest contrast. Putting complementary colors together will give people a strong sense of rejection. If mixed together, it will bring out a turbid color. For example, red and blue, blue and yellow, green and magenta are complementary colors.
Contrast color can also be defined as: two colors that can be clearly distinguished are called contrast colors. Including hue contrast, lightness contrast, saturation contrast, cold and warm contrast, complementary color contrast, color contrast and achromatic contrast. It is an important means to form obvious color effect, and it is also an important method to give color expression. Its manifestations can be divided into simultaneous comparison and successive comparison.
For example, yellow and blue, purple and green, red and blue, any color and black, white, gray, dark and bright, cold and warm, bright and dark are all contrasting colors.
