What's CIE1976 chromaticity Coordinates u', v' ?

In the CIE chromaticity diagram of each point represents a clear color. But for the human eye position when the color change is very small, and we cannot feel the change, and that is similar to the original color of each color. Although accounting for the position of a point in a chromaticity diagram, but the actual vision, it is actually a small range, wide capacity this is known as the color.

For an ideal color intensity map, no matter in what position is MacAdam small ellipse can form equal radius of the circle and its center coordinate as a representative, in order to achieve this goal, in 1976 years in the CIE color space system space system correction will make corrections, XY color coordinates to 2 a linear transformation of the mode conversion to the new u 'V' coordinates.
