What does a indicate in the CIE L * a * b * color space?

The letters L*, a* and b* represent each of the three values the CIELAB color space uses to measure objective color and calculate color differences. L* represents lightness from black to white on a scale of zero to 100, while a* and b* represent chromaticity with no specific numeric limits.

Why is CIELAB better than RGB?

Unlike the RGB and CMYK color models, CIELAB is designed to approximate human vision. The L* component closely matches human perception of lightness, though it does not take the Helmholtz–Kohlrausch effect into account. CIELAB is less uniform in the color axes, but is useful for predicting small differences in color.

What does L * A * B stand for?

What does L*a*b* stand for? Regardless of the which color space name you call it, it's important to know what L*, a*, and b*stand for. L*: Lightness. a*: Red/Green Value. b*: Blue/Yellow Value.

What does lab stand for in CIELAB?

The color space CIE L, a, b - where CIE means International Commission on Illumination - or simply LAB, is the basic mode used by the ICC profiles.
