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.
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.
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 ...
The conventional gradient colors of the rainbow symbol. ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet. There are several mnemonics that can be used for remembering this color sequence, such as the name "Roy G. Biv" or sentences such as " Richard of ...
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. [2] It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength that’s between approximately ...
The flower of the amaranth plant. Amaranth is a reddish-rose color that is a representation of the color of the flower of the amaranth plant. The color shown is the color of the red amaranth flower (the color normally considered amaranth), but there are other varieties of amaranth that have other colors of amaranth flowers; these colors are also shown below.
Magnolia is a color named after the flowering plant of the genus Magnolia. As magnolias have flowers of more than one color, mainly cream or pale purple, magnolia may refer to different colors in different countries. An early use of magnolia as a colour name in English was in 1880, describing it as a "tint of cream-color". [1]
The NCS color model is based on the three pairs of elementary colors ( white – black, green – red, and yellow – blue ), as defined by color opponency. The Natural Color System ( NCS) is a proprietary perceptual color model. It is based on the color opponency hypothesis of color vision, first proposed by German physiologist Ewald Hering. [1]
