Compared to a similar treatment in RGB color space, the LAB color method, being based on human perception, delivers more impression

LAB or CIELAB is a colorspace. It is designed to be perceptually uniform with respect to human color vision.

L* represents lightness

a* and b* for the green–red and blue–yellow

Playing on curves creatively in this environment give an intense, tangy touch of chromatic contrast.


These three images are the result of similar treatment, this time in RGB color space.
