New online: Color Appearance Comparison under different illuminants
Colors do not just appear different because we perceive them differently.
They also change in appearance depending on the light source under which they are viewed.
That is exactly what this new tool is about:
a compact comparison view that shows how a color behaves under different illuminants — side by side, both visually and analytically.
What makes it useful:
- multiple standard illuminants compared at a glance
- additional interpretation through color difference
- reference relative to D50
- option to test a custom illuminant
To me, this is a meaningful step away from static color values and toward a perspective that considers light, observation, and color appearance together.

Custom Illuminant
Upload a BabelColor PatchTool ambient measurement file (.txt) to estimate how the configured base color appears under that illuminant.
