This color space is a mathematical representation of the human eye's
response to color. Note that this color space is non-linear! It's a 3-D
model that is "unfolded" like a Mecador projection map of the earth.

LAB color is the same model revised to be a linear color space. This model
works best to define color on a computer because of its linear nature. A
and B define the hue and saturation of the color where the L value or
"Luminance" comprises the Z axis through the middle. The 0,0 point of the
diagram is the "white reference" and defined as the color temperature. With
the xyY defination of LAB (See "Printing Inks Setup" in Photoshop), the Y
value can be calcu
