What are the three primary colors in art?

The three primary colors in art refer to red, green and blue.

RGB color model (English), also known as RGB color model, is an additive color model, which adds RGB colors in different proportions to produce multi-color light.

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: different devices detect and reproduce specific RGB values differently, because color substances (fluorescent agents or dyes) and their individual response levels to red, green and blue vary from manufacturer to manufacturer, and even the same device has different time.

The three primary colors of color light refer to red, green and blue, and their corresponding frequencies are 428.6THz, 549.3THz and 688.4THz respectively, which are converted into air wavelengths of 700nm, 546. 1nm and 435.8nm respectively. The three primary colors of light and objects are different. The three primary colors of light can be mixed in a certain proportion to present various light colors.

Principle of tricolor:

The human eye is most sensitive to red, green and blue. The human eye is like a three-color receiver system, and most colors can be synthesized by different proportions of red, green and blue. Similarly, most monochromatic light can also be decomposed into three colors: red, green and blue, which is the most basic principle of colorimetry, also known as the trichromatic principle.

Color holographic display is actually a three-dimensional color image transmission technology. According to the principle of colorimetry, most colors in nature can be mixed by red light, green light and blue light in a proper proportion, so red light, green light and blue light are called three primary colors. Therefore, the color recording and reproduction of color holograms is essentially the recording and reproduction of three primary colors.
