* Cielab or CIE 1976 L*a*b is a chromatic value color space used to describe all the colors that the human eye can perceive. * This Color Lab model is three dimensional and the three parameters in the model represent the lightness of color (L *), its position between red and green (a *, negative values indicate green while positive values indicate red) and its position between yellow and blue (b *, negative values indicate blue and positive values indicate yellow). * The conversion from Color Lab to RGB depends on the device used and for this app it has been used the illuminant D65 and observer at 2º.
* The direct interpretation of the values obtained of a Color Lab is not easy and this app helps the visual interpretation of these parameters. * The application allows the visualization on the same screen of up to three Color Lab results so you can compare visually instead of numerically.
