Learn about the RGB color model, an additive color model that uses red, green and blue light to reproduce a wide range of colors. Find out how the RGB model works, how it differs from subtractive color, and how it relates to human vision and devices.
This web page provides a comprehensive overview of different color spaces and their applications, based on various color models and human perception. It includes the YUV color space, which is a component of the YUV color model, used for encoding and decoding video signals.
A secondary color is a color made by mixing two primary colors of a given color model in even proportions. Learn about the different types of secondary colors, tertiary colors, and quaternary colors in traditional and modern color theory, and see how they are applied in RGB and CMYK color models.
A color space is a specific organization of colors based on a color model and a mapping function. Learn about the origins of the color-space concept, the different types of color spaces, and how to convert colors between them.
Learn about the different varieties and meanings of the color red in various color systems, such as RGB, CMYK, Crayola, Munsell, and NCS. See examples of red colors and their spectral coordinates, hex codes, and ISCC–NBS descriptors.
Learn about the different color palettes used to produce black-and-white and RGB color pictures by a computer's display hardware. See examples of monochrome (1-bit to 8-bit), dichrome (16-bit RG), and full RGB (24-bit) formats.
Learn about the definition, applications and specifications of RGB color spaces, a category of additive colorimetric color spaces based on the RGB color model. Compare different RGB color spaces such as NTSC, PAL, sRGB, Adobe RGB, Rec. 2020 and more.
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
