Introduction - Introduction
All of our Gold processes are controlled by CIE parameters, which refer to the colour appearance of the deposit for which the eye responds to. Created by the International Commission on Illumination (CIE), the index uses three characteristic units on a sphere of colours.
L * a* b* are colorimetric values, which are:
- L for lightening: from white (i.e Silver to dark)
- (+) a for red colour (-) a for green colour
- (+) b for yellow colour (-) b for blue colour.
This international standard is set to facilitate the communication among users, i.e. Design, Fashion and Luxury industries.
