What color and what color make purple? What color plus green can become pink? Can it be pink?

All colors are composed of three primary colors, red, yellow and blue are the primary colors, and red plus yellow is orange. Red plus blue is purple. Yellow plus blue is green. Red, yellow and blue add up to black. The depth of color is determined by different proportions.

To lighten the color, you can also add white. So green can't be pink with everything. Pink is white with a little red. These principles are universal for oily paints and water-based color pastes.

Extended data

Three primary colors refer to the three basic colors that cannot be decomposed. What we usually call three primary colors, namely magenta, yellow and cyan (cyan is not blue, and blue is a mixture of magenta and cyan).

The three primary colors can be mixed into various colors and add up to white at the same time. Black, white and gray belong to colorless system.

Three-color light model (English: RGB color model), also known as RGB color model or red, green and blue color model, is an additive color model, which adds red, green and blue colors in different proportions to produce various colors of light.

Tricolor painting

The main purpose of RGB color model is to detect, represent and display images in electronic systems (such as televisions and computers), but it is also used in traditional photography.

Before the electronic age, based on human perception of color, RGB color model has a solid theoretical support.

RGB is a device-dependent color space: because of color substances (fluorescent agents or dyes), different devices detect and reproduce specific RGB values differently.

And their individual response levels to red, green and blue are different from different manufacturers, even the same equipment at different times.
