L a b is a color space standardized by the Commission Internationale de l'Éclairage (CIE) and represents color using three values: L for lightness, a for the green-red components, and b for the blue-yellow components.
Here's a breakdown:
-
*L:** Represents the lightness of the color, ranging from 0 (black) to 100 (white).
-
*a:** Represents the color's position on the green-red axis. Negative values indicate green, while positive values indicate red.
-
*b:** Represents the color's position on the blue-yellow axis. Negative values indicate blue, while positive values indicate yellow.
This color space is designed to be perceptually uniform, meaning that equal numerical differences correspond to roughly equal perceived differences in color. This makes it useful for color management, quality control, and other applications where accurate color reproduction is important.
