Detailed Description
A Lab color space is a CIE-based ABC color space with two transformation stages.
In this type of space, A, B, and C represent the L*, a*, and b* components of a CIE 1976 L*a*b* space. The range of the first (L*) component is always 0 to 100; the ranges of the second and third (a* and b*) components are defined by the Range.

Constructor & Destructor Documentation
LabColorSpace
LabColorSpace(System.Collections.Generic.IList< System.Double > whitePoint)Parameters
whitePoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.
Create a Lab color space.
The blackPoint defaults to [0.0, 0.0, 0.0].
The range defaults to [-100 100 -100 100]

LabColorSpace(System.Collections.Generic.IList< System.Double > whitePoint, System.Collections.Generic.IList< System.Double > blackPoint, System.Collections.Generic.IList< System.Double > range)Parameters
whitePoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.
blackPoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point. All three of these numbers must be non-negative.
range: System.Collections.Generic.IList< System.Double >An array of four numbers [ amin amax bmin bmax ] specifying the range of valid values for the a* and b* (B and C) components of the color space.
Create a Lab color space.
