5.1 L*a*b* Color Space Overview
A good understanding of the L*a*b* color space can be helpful when using
Separation Management.
Separation Management.
L*a*b* refers to a three dimensional color space model. L* indicates on a scale of 0
to 100 the luminosity/brightness of a color ranging from dark to light; a* indicates
on a scale of -120 to +120 the appearance of a color ranging from green to red; b*
indicates on a scale of -120 to +120 the appearance of a color ranging from blue to
yellow.

Every color has a specific L*a*b* value. A spectrophotometer defines a color
according to its location in three-dimensional L*a*b* color space. For example, you
can use a spectrophotometer to measure custom color chips to determine the correct
L*a*b* values for your desired custom color.
