CIELAB color space, also called L*A*B*, is defined by the International Commission on Illumination. is a defined color space. This encoding expresses the color as three values:
CIELAB is designed as a perceptually uniform field, where a given numerical change corresponds to a similar perceived change in color. While the L*A*B* area is not truly perceptually uniform, it is used in industry to detect small color differences.
In the L*A*B* color space, L* denotes lightness, and A* and B* are the chromaticity coordinates. A* and B* are the color directions: +A* is the red axis, -A* is the green axis, +B* is the yellow axis, and -B* is the blue axis. The area around the center represents achromatic colors, and the color saturation increases as you move outward.
The A* axis runs from left to right. A color measurement movement in the +A direction indicates a shift towards red. Along the B* axis, the +B movement represents a shift towards yellow. The central L* axis shows L = 0 (black or total absorption) at the bottom. In the center of this plane is neutral or gray.
CIELAB or CIE L*A*B* is a device-independent three-dimensional color space that allows accurate measurement and comparison of all perceptible colors using three color values. In this color space, the numerical differences between values roughly correspond to the amount of variation people see between colors.
In short, the CIE color model is a mapping system that uses the combination of three color values close to red / green / blue drawn in three dimensions in space. When these values are combined, every color that the human eye can perceive can be reproduced.
The CIE color model was first created in 1931 to map all the colors perceived by the human eye. It is designed independently of any technology capable of presenting color, so it is considered the most accurate color model.
Our organization also provides L*A*B* color analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
