Shades of yellow
Introduction Varieties of the color yellow may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a yellow or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Web colors ===Yellow (RGB) (X11 yellow) (color wheel yellow)===Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. 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 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.===Yellow (CMYK) (process yellow) (canary yellow)===Cyan, magenta, and yellow are the three subtractive primary colors used in printing. '''Process yellow''' (also called '''pigment yellow''' or '''printer's yellow'''), also known as '''canary yellow''', is one of the three colors typically used as subtractive primary colors, along with magenta and cyan. Canary yellow is derived from the colour of an average canary bird, though canaries can vary in colour from dark yellow to light pink.Process yellow is not an RGB color, and in the CMYK color model there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure yellow ink.The first recorded use of ''canary yellow'' as a color name in English was in 1789.===Yellow (NCS) (psychological primary yellow)===Approximations within the sRGB gamut to the primary colors of the Natural Color System, a model based on the opponent process theory of color vision.The color defined as '''yellow''' in the NCS or Natural Color System is shown at right (NCS 0580-Y). The Natural Color System is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.The “Natural Color System” is widely used in Scandinavia.===Yellow (Munsell)===The color defined as '''yellow''' in the Munsell color system (Munsell 5Y) is shown at apex of color wheel. The ''Munsell color system'' is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity), spaced uniformly in three dimensions in the elongated oval at an angle shaped Munsell color solid according to the logarithmic scale which governs human perception. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five primary colors—red, yellow, green, blue, and purple.The Munsell colors displayed are only approximate as they have been adjusted to fit into the sRGB gamut.===Yellow (Pantone)===The color that is called '''yellow''' in Pantone is displayed at right.The source of this color is the "Pantone Textile Paper eXtended (TPX)" color list, color #C, EC, M, PC, U, or CP—Yellow.

It is often used on hazard symbols, warning signs, guard rails, dangerous equipment, older American civil defense sirens (typically from the 1950s and 1960s), and some high-visibility clothing and personal protective equipment.
