4.6.7.8.3 Color model LAB
LAB or L*a*b*-color model is built from a three dimensional coordinate system:
Fig. 210: Color model LAB
a*-axis describes the red and green components of a color, negative values stand for greenand positive
values stand for red. Range of values from -150 to +100.
b*-axis describes the blue and yellow components of a color, negative values stand for blue positive values
stand for yellow. Range of values from -100 to +150.
L*-axis describes the lightness of the color with values from 0 to 100.
One of the most important properties of the L*a*b color model is the independency from the technology
used for capturing and displaying the images.
LAB values are calculated from linear RGB values. This is based in a D65 illuminant and a 2° observer.
