What is lab in image processing?
Lab color space is a 3-axis color system with dimension L for lightness and a and b for the color dimensions. Working with the Lab color space includes all of colors in the spectrum, as well as colors outside of human perception.

What is the a axis in CIE L * a * b?
a* and b* are color directions: +a* is the red axis, -a’ is the green axis, +b* is the yellow axis and -b* is the blue axis. Area around the center represents achromatic colors and moving outwards, color saturation increases.
