The concept of a color system with a hue was explored as early as 1830 with Philipp Otto Runge's color sphere. The Munsell color system from the 1930s was a great step forward, as it was realized that perceptual uniformity means the color space can no longer be a sphere. As a convention, the hue for red is set to 0° for most color spaces with ...
When lightening a color this hue shift can be corrected with the addition of a small amount of an adjacent color to bring the hue of the mixture back in line with the parent color (e.g. adding a small amount of orange to a mixture of red and white will correct the tendency of this mixture to shift slightly towards the blue end of the spectrum).
Color is an element consisting of hues, of which there are three properties: hue, chroma or intensity, and value. [3] Color is present when light strikes an object and is reflected back into the eye, a reaction to a hue arising in the optic nerve. [6] The first of the properties is hue, which is the distinguishable color, like red, blue or ...
A color is fully specified by listing the three numbers for hue, value, and chroma in that order. For instance, a purple of medium lightness and fairly saturated would be 5P 5/10 with 5P meaning the color in the middle of the purple hue band, 5/ meaning medium value (lightness), and a chroma of 10 (see swatch).

HSV (hue, saturation, value), also known as HSB (hue, saturation, brightness) is often used by artists because it is often more natural to think about a color in terms of hue and saturation than in terms of additive or subtractive color components. HSV is a transformation of an RGB color space, and its components and colorimetry are relative to ...
Colors in the NCS are defined by three values, expressed in percentages, specifying the degree of blackness (s, = relative visual similarity to the black elementary color), chromaticness (c, = relative visual similarity to the "strongest", most saturated, color in that hue triangle), and hue (Φ, = relative similarity to one or two of the ...
There are three properties of color: hue, brightness or chroma, and value. Hue is the name of a color (red, yellow, and blue, etc.). Brightness and chroma refer to the intensity and strength of the color. A high chroma color is more pure and less greyed than a low chroma color. The lightness or darkness to a color is the value.
