What are the tips for PU color paste toning? Next, the PU color paste manufacturer will introduce to you:
1. The three elements of color: hue, lightness, saturation.
1 Hue (H), also known as hue, is the main characteristic of color and the main difference between colors, just as apples are red, lemons are yellow, and the sky is blue.
2. Brightness (V), also known as color value, is simply the difference between the lightness and darkness of a color.
3. Saturation (C) is also known as chroma, purity, that is, the difference between vividness.
2. The basic principle of color matching:
Red, yellow and blue are called the three primary colors. Two primary colors are combined into secondary colors, and there are three secondary colors. The color produced by mixing two colors is a complex color.
    Primary colors: red yellow blue red yellow
    Secondary color: orange green purple orange
    Complex color: yellow gray basket gray red gray
In addition, on the basis of the primary color or secondary color, by diluting with white, light red, pink, light blue, lake blue and other shades of different colors can be prepared; adding different amounts of black can be adjusted to produce brown, dark brown, Dark green and other colors with different brightness. Therefore, white and black are often called vanishing colors.
A brief introduction to the triangular color matching method based on the above principles. The three vertices of the triangle are the primary colors of red, yellow, and blue, and a series of intermediate tones obtained by mixing the two primary colors can be found on the sides. Such as: basket gray, jujube red and so on. Please be careful to avoid using the three primary colors of red, yellow and blue at the same time, that is, to avoid the black in the center area of the triangle. At the same time, when you need to use multiple colors, try to stay away from the center area, otherwise the adjusted color will be eclipsed. For example, it is impossible to get a bright olive green with purple and lemon yellow, but a bright olive green can be obtained by using lemon yellow and orange instead.
