WebThe CIE Lab color space has three components: L* and a* and b*. The L* component defines how light the color is (therefore it is limited to 0-100 range), the higher the lightness, the more white it appears. The lower the lightness, the closer it is to black. Meanwhile, the a* component defines how red or green the color appears.
