CIELAB (L*a*b*) is a perceptually uniform color space defined by the International Commission on Illumination. L* represents lightness (0–100), a* encodes the green-to-red axis, and b* encodes the blue-to-yellow axis. LAB is device-independent, making it ideal for color science, image processing, and accurate color matching across different media.
