In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves , corn , canaries , daffodils , and lemons, as well as egg yolks , buttercups , and bananas.
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.
A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is black; if all are at maximum, the result is the brightest ...
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.
This list of monochrome and RGB palettes includes generic repertoires of colors (color palettes) to produce black-and-white and RGB color pictures by a computer's display hardware. RGB is the most common method to produce colors for displays; so these complete RGB color repertoires have every possible combination of R-G-B triplets within any ...
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
A color model is a conceptual model and does not have specifically defined primary colors. A color space based on the RGB color model, most commonly sRGB, has defined primaries and can be used to visualize the color mixing and yield approximate tertiary colors. Also note that the color terms applied to tertiary and quaternary colors are not ...
