A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Gradient RGB/CMY color wheel Seven-color and twelve-color color circles from 1708, attributed to Claude Boutet Wilhelm von Bezold's 1874 Farbentafel. A color wheel or color circle is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc.
In the RGB model, the primary colors are red, green, and blue. The complementary primary–secondary combinations are red – cyan, green – magenta, and blue – yellow. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain ...
On the RGB color wheel, "azure" (hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model , used to create all the colors on a television or computer screen, azure is created by adding a little green light to blue light.
In the RGB model, hues are represented by specifying one color as full intensity (255), a second color with a variable intensity, and the third color with no intensity (0). The following provides some examples using red as the full-intensity and green as the partial-intensity colors; blue is always zero: Red. Green.
The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space. This color is also called color wheel yellow. It is at precisely 60 degrees on the HSV color wheel, also known as the RGB color wheel (Image of RGB color wheel:). Its complementary color is blue.
Description. RGB color wheel.svg. English: Color star using the RGB color model Own work based on: Color star-en.svg and An existing RYB image. This model uses names for hues that are uncommon in color theory and do not reflect standard hue naming. To avoid confusion, please refer to accurate color wheels that use the standardized names.
RGB color spaces are well-suited to describing the electronic display of color, such as computer monitors and color television. These devices often reproduce colours using an array of red, green, and blue phosphors agitated by a cathode ray tube (CRT), or an array of red, green, and blue LCDs lit by a backlight, and are therefore naturally ...
