What is LAB Code?

LAB is a perceptually uniform color space defined by the International Commission on Illumination (CIE). It consists of three components: L* (Lightness) ranging from 0 to 100, a* (green-red axis) ranging from -128 to 127, and b* (blue-yellow axis) ranging from -128 to 127. LAB color space encompasses all perceivable colors and is device-independent, making it ideal for color management and professional image editing. The LAB color space is designed to approximate human vision and provides consistent color representation across different devices.

Structure:

LAB is represented with L* (Lightness 0-100), a* (green-red axis -128 to 127), and b* (blue-yellow axis -128 to 127).

Examples:

  • LAB(53, 80, 67) - Pure Red
  • LAB(88, -86, 83) - Pure Green
  • LAB(32, 79, -108) - Pure Blue
  • LAB(100, 0, 0) - White
  • LAB(0, 0, 0) - Black

What is LCH Code?

LCH is a cylindrical representation of the LAB color space, using Lightness, Chroma, and Hue components. Lightness ranges from 0 to 100, Chroma represents color intensity (0 to ~134), and Hue represents the color angle (0-360 degrees). LCH is more intuitive than LAB for color manipulation as it separates lightness from color information. It's particularly useful in color grading, print production, and advanced color correction workflows where precise color control is required.

Structure:

LCH is represented as L (Lightness 0-100), C (Chroma 0-134), and H (Hue 0-360°), providing a cylindrical representation of LAB color space.

Examples:

  • LCH(53, 104, 40) - Pure Red
  • LCH(88, 119, 136) - Pure Green
  • LCH(32, 133, 306) - Pure Blue
  • LCH(100, 0, 0) - White
  • LCH(0, 0, 0) - Black

Logic behind LAB to LCH Conversion

LAB to LCH conversion involves mathematical transformation between color spaces. The conversion process typically uses intermediate RGB values when direct conversion formulas are not available. LAB values are first normalized to standard ranges, then transformed using colorimetric equations specific to each color space. The conversion maintains perceptual color accuracy through proper gamma correction and color space mapping algorithms.

Frequently Asked Questions

What is the difference between LAB and LCH color formats?
LAB is perceptually uniform primarily used for color science and image processing, while LCH is cylindrical LAB format commonly used for color correction and professional imaging. Each format has specific advantages for different applications.
Are the converted LCH values accurate for professional use?
Yes, our converter uses industry-standard algorithms to ensure mathematically accurate conversions suitable for professional design and development work.
Can I convert multiple LAB values at once?
Currently our tool converts one color at a time for maximum accuracy. For bulk conversions, you can use the tool repeatedly or contact us for enterprise solutions.
Will the converted color look exactly the same as the original?
Our converter maintains color accuracy within the capabilities of each color space. Some conversions may have minor variations due to color space limitations.
