The CIELAB color space (also known as CIE L*a*b* or sometimes informally abbreviated as "Lab") is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976.
It expresses color as three values: L* for the lightness from black (0) to white (100), a* from green (−) to red (+), and b* from blue (−) to yellow (+).
CIELAB was designed so that the same amount of numerical change in these values corresponds to roughly the same amount of visually perceived change.
