RGB to LAB Converter

Convert RGB colors to LAB color space. LAB is perceptually uniform, making it ideal for color-critical applications.

About LAB Color Space

What is LAB Color?

LAB color space is a device-independent model that describes all perceivable colors. It consists of:

  • L* (Lightness): 0 (black) to 100 (white)
  • a*: -128 (green) to +127 (red)
  • b*: -128 (blue) to +127 (yellow)

Why Use LAB?

  • Device-independent color representation
  • Perceptually uniform color space
  • Ideal for color matching systems
  • Perfect for measuring color differences
  • Used in professional color management

Common Applications

  • Professional photography and image editing
  • Print and packaging design
  • Color quality control in manufacturing
  • Digital art and design
  • Scientific color analysis

Understanding LAB Values

L* (Lightness): Represents the perceived brightness, from darkest black (0) to brightest white (100).

a* (Green-Red): Represents the position between green (-128) and red (+127).

b* (Blue-Yellow): Represents the position between blue (-128) and yellow (+127).
