Color Definitions

Color consists of three characteristics; luminance (intensity), hue, and saturation.

Color luminance is the wavelength (spectral radiance) and it’s conversion to luminance values.

Hue is the dominant wavelength of color as subjectively perceived by the human eye

Saturation is the degree to which the hue of the color is undiluted by its complimentary color to form white

Uniformity (or the lack thereof), is the gradual change of brightness (luminance) and/or color (chrominance) from one area of a display to another
