LAB (Color-Space)

(CIELAB).

  • Development: Introduced by the Commission Internationale de l’Éclairage (CIE) in 1976 to create a color space that approximates human vision more accurately than RGB or CMYK.
  • Colors/Units of Measure: L* (lightness), a* (green to red), b* (blue to yellow).
  • Hardware-Based: Mainly used in software applications for color management, image processing, and scientific research.
  • Year of Release: Developed by the CIE in 1976.
  • Founding Institution: Commission Internationale de l’Éclairage (CIE).
  • Color Theory: Lab color space is based on human vision and perception, with L* representing the lightness of a color, a* representing the position between green and red on the color axis, and b* representing the position between blue and yellow on the color axis.
  • Color Model: Perceptually uniform color space.
  • Total Number of Possible Color Combinations: Infinite range of colors, covering the entire visible spectrum.
  • Primary Colors: Not applicable, as Lab is a perceptual color space rather than a color mixing model.
  • Secondary Colors: Not applicable.
  • Tertiary Colors: Not applicable.
