In 1975 the CIE (International Commission on Illumination) proposed a new system to standardize and simplify communication about hues, regardless of measuring instrument and lighting conditions. The CIELAB system works to this day as a point of reference in seller-customer relations. It is a color space that best simulates the human perception of color differences. Each color acquires 3 color coordinates. In the CIELAB system these coordinates are L*, a* and b* and are depicted in a three-dimensional coordinate system.<\/p>\n
The L* (lightness) coordinate corresponds to the brightness value and takes values \u200b\u200bfrom 0 (black) to 100 (white), while the a* and b* coordinates correspond to the color information, without their values \u200b\u200bhaving numerical limits. The value of a* gives the position of the color between green and red (smaller value of a* tends to green, larger tends to red). Accordingly, the value of b* gives the position between blue and yellow (smaller b* value tends towards blue, larger towards yellow).<\/p>\n
The combination of the three coordinates always describes the same color regardless of the lighting and observation conditions (due to the measuring instruments \u2013 device independent). In the paint industry, the CIELAB system is used in the quality control of shades, the research of new recipes, the creation of a database of color systems and comparison with the competition.<\/p>\n
