About RGB and CIELAB
An RGB value combines Red, Green, and Blue light values from 0 to 255. It is device-dependent and optimized for monitors and displays.
The CIELAB (L*a*b*) color space expresses color as three numerical values: lightness ($L*$), and green–red ($a*$) and blue–yellow ($b*$) color-opponent dimensions. It is device-independent and designed to approximate human vision uniformly.
