CIELAB Color Space Diagram - Understanding Perceptual Color Differences #2007966 (License: Personal Use)

This image visualizes the CIELAB (L*a*b*) color space as a 3D model, where the L* axis (lightness) is implied by depth, while the a* (green to red) and b* (blue to yellow) axes form the horizontal plane. The colorful inner surface represents achievable colors within standard gamuts, bounded by the outer translucent shell indicating theoretical limits. Grid lines emphasize perceptual uniformity-equal distances correspond to roughly equal perceived color differences.

Used in color science education, digital design resources, and software documentation (e.g., Adobe Color, ICC profiles) to explain color difference metrics like ΔE. Targets users seeking to understand color accuracy, calibration, or gamut mapping.
