HueIn nature, almost all light is mixed with different wavelengths. The human mind approximates mixed light from the visible spectrum from 380 to 740 nanometers as a color. Random wavelengths of light that contain great variation are perceived as white or as a light color. Mixtures of wavelength of similar length are often perceived as a bright color that is free of white. These are known as hues and are considered pure colors.
Spectral ColorsSpectral colors are hues that correspond to a single wavelength of light or narrow band of wavelengths. These exist on a continuum based on wavelength that spans from violet, blue, cyan, green, yellow, orange to red.
PigmentsIn painting theory, a hue is a pigment that has not been mixed. From this perspective, unmixed pigments are pure colors.
SaturationSaturation is the intensity and purity of a color. A laser light is the most saturated color because it can be based on a narrow wavelength and be extremely intense. A color that is pure and intense can be described as heavily saturated. A saturated color appears bright against both a white and black background due to its intensity and lack of grey content. For example, a neon green highlighter pen that is highly visible on both white and black paper.
ShadesA shade is any hue that has been mixed with black. This is less pure than the hue itself.
TintsA tint is any hue that has been mixed with white. This is less pure than the hue itself.
ToneA tone is any hue that has been mixed with both white and black. In other words, a hue that has been mixed with grey. This is less pure than the hue itself.
|Overview: Color Purity|
The degree to which a color is free of white and black.
The degree to which a color pigment is unmixed with anything that changes its color.
