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.
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.
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.[2]
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.
Gold, also called golden, is a yellow-orange color which is a representation of the color of the elementgold.
The web color gold (also referred to as orange-yellow) is sometimes referred to as golden to distinguish it from the color metallic gold. The use of gold as a color term in traditional usage is more often applied to the color "metallic gold".
The first recorded uses of golden as a color name in English were in 1300 to refer to the element gold and in 1423 to refer to blonde hair.[8]
Safety yellow is one of the standard high-visibility safety colors defined by ANSI standard Z535, which specifies standards for safety and accident prevention information. 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. The definition is mirrored in British Standard BS 381C and Australian Standard AS2700 (where it is known as golden yellow). In 1937, it was determined that safety yellow was the best color to be noticed by the human brain; as a result, the paint color of all United States school buses was changed from orange to safety yellow (see also school bus yellow).
Displayed at right is the color green earth. It is also known as terre verte and Verona green. It is an inorganic pigment derived from the minerals celadonite and glauconite.[16][17]
