Achieve True Color Consistency with LAB to Hex
Most color spaces (RGB, CMYK) are flawed because they depend on the device displaying them. A screen's "Red" might be different from a phone's "Red". The **LAB to Hex Converter** at **Online Tool Base** allows you to work with the **CIE L*a*b*** color space—the most complete color model that describes how the human eye actually perceives color—and translate it into web-ready Hex codes.
Why LAB Matters
LAB is "device-independent". It is used in high-end industries like plastics, textiles, and automotive paint because distinct LAB values always mean the exact same color. Web designers are increasingly adopting LAB concepts (via CSS Color Level 4) to ensure that their brand colors look consistent across different monitors and lighting conditions.
The Axes Explained
- L (Lightness): A value from 0 (Black) to 100 (White). This is true perceptual brightness.
- a (Green-Red): Negative values are green; positive values are red.
- b (Blue-Yellow): Negative values are blue; positive values are yellow.
How to Use
- Input your scientific LAB values (e.g., L:50, a:20, b:-15).
- The tool performs the complex transformation Matrix (LAB -> XYZ -> Linear RGB -> Gamma Corrected sRGB).
- It outputs the standard 6-digit Hex code.
- Copy the code for use in your CSS or HTML.
