How many colors can be created from the three primary colors of red, yellow and blue?

Under normal circumstances, the three primary colors of red, yellow and blue are difficult to create other standard colors with gouache...

Red + yellow = orange; red + blue = purple; blue + Yellow = green; red + yellow + blue = black.

Pink lemon yellow = lemon yellow + pure white; Garcinia = lemon yellow + rose red; orange = lemon yellow + rose red; earthy yellow = lemon yellow + pure black + rose red; ripe brown = Lemon yellow + pure black + rose red; pink rose red = pure white + rose red; vermillion = lemon yellow + rose red; dark red = rose red + pure black; purple = pure purple + rose red? Chu Shihong = rose red + lemon yellow + pure black; powder blue = pure white + sky blue; teal = grass green + sky blue.

Extended information:

The three primary colors refer to the three basic colors that can no longer be decomposed. The three primary colors we usually refer to are magenta, yellow, and cyan (green, not blue, blue It 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 mixed color of the three primary colors of pigments is black, while the mixed color of the three primary colors as a light-based material is white due to the special properties of light.

Introduction to primary colors

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

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.

The three primary colors of light

The light will become brighter and brighter. Mixing two or two can get a brighter intermediate color: red, medium green, ultramarine. Combining the three in equal amounts can get white.

Complementary color means that it does not contain another color at all. Red and green are mixed to form yellow. Because it does not contain blue at all, yellow is the complementary color of blue. Yellow is obtained when red and green are mixed in a certain proportion. Therefore, yellow cannot be called the three primary colors.
