Are the three primary colors red, yellow and blue or red, green and blue, or do red, yellow and blue and red, green and blue have different paths?

The three primary colors refer to the three basic colors that can no longer be decomposed. What we usually call the three primary colors are magenta, yellow, and cyan (is it cyan, not blue, and blue is a mixture of magenta and cyan)? . The three primary colors can be mixed to produce all colors and add up to black at the same time. Black, white and gray are colorless systems.

The three primary color light model (English: RGB color model), also known as the RGB color model or the red, green and blue color model, is an additive color model that combines red (Red), green (Green), and blue ( The three primary colors (Blue) are added in different proportions to produce a variety of colors.

The main purpose of the RGB color model is to detect, represent and display images in electronic systems, such as televisions and computers, but it also has applications in traditional photography. Before the electronic age, the RGB color model already had solid theoretical support based on human perception of color.

RGB is a device-dependent color space: different devices detect and reproduce specific RGB values ??differently because of the color substances (fluorophores or dyes) and their effects on red, green, and blue. The individual response levels vary from manufacturer to manufacturer and even from time to time for the same device.

Color mixing principles

The color is like cooking, you need to control the heat. If the colors are not blended enough, it will appear "raw" and "angry".

The variety of pigments should be used as little as possible. Including black and white, generally no more than four colors can be mixed to produce the required color. Adding the fifth or more colors can only increase the blackness. Together with the role of gray, the contrasting colors in the color are black and gray.

Some people think that adding different pigments can enrich the colors, but in fact it can only reduce the purity. Experienced painters often use a few simple colors to achieve beautiful and elegant effects.

Use light yellow and add a small amount of black to create a calm green. When the colors are mixed properly, there will be a feeling of moisture. When applied to the canvas, the pigments will seep into the picture and retreat into the space. On the contrary, the colors will appear dry and floating, which is not good.

According to the ingredients contained in the pigment, color can be divided into pure color, clear color and turbid color. A pure color does not contain white, a clear color contains only black, or only white, and a turbid color ("gray" color) contains both black and white, that is, it contains gray.

The "grey color" we talk about when painting has two meanings: one refers to achromatic gray; the other refers to turbid color. It does not refer to the gray mixed with black and white, but refers to a color that is subtle and calm and contains a certain gray component. The purpose of using a lot of "gray colors" on the picture is to make the colors of the picture stand out against each other louder.

Color painters should be proficient in color mixing techniques, make sure that the color to be mixed is a solid color (gray color), and then mix colors according to the color mixing principles of different types of colors.
