Hexadecimal 8-bit RGB representations of the main 125 colors. 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.
Pure yellow light is composed of equal amount of red and green light. 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 evoked by light with a dominant wavelength of roughly 575–585 nm. It is a primary color in subtractive color systems, used in painting or color printing. 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.

The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected.
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
Saffron is a shade of yellow or orange, the colour of the tip of the saffron crocus thread, from which the spice saffron is derived. [2] The hue of the spice saffron is primarily due to the carotenoid chemical crocin .
RGB and CMYK color systems. ISCC–NBS descriptor. Vivid yellowish green. B: Normalized to [0–255] (byte) H: Normalized to [0–100] (hundred) Chartreuse ( US: / ʃɑːrˈtruːz, - ˈtruːs / ⓘ, UK: /- ˈtrɜːz /, [1] French: [ʃaʁtʁøz] ⓘ ), also known as yellow-green or greenish yellow, is a color between yellow and green.

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 ...
RGB color spaces are additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model. [2] RGB color spaces are commonly found describing the mapping of the RGB color model to human perceivable color, but some RGB color spaces use imaginary (non-real-world) primaries and thus can not be ...
