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.

Wrapping the spectrum into a color wheel[edit]

In a color proximity sense, a primary color has a color range of 120° (60° on each side of the color's hue) and any color has to be within that range to be considered a variation of that color. Secondary colors have a color range of 60° (30°), tertiary colors have a color range of 30° (15°), quaternary colors have a color range of 15° (7.5°), quinary colors have a color range of 7.5° (3.75°), and so on. Because yellow is located at a hue angle of 60°, it has a tertiary color range of 45° and 75°, and any color out of this range is more related to orange or chartreuse than yellow. If the visible spectrum is wrapped to form a color wheel, yellow (subtractive primary) appears midway between red and green:

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.

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 hues of the Munsell color system, at varying values, and maximum chroma to stay in the sRGB gamut.

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.

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, 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).
