Color concept
Metamerism
When different spectral mixtures look like the same color under some conditions.
Core concept Color perception future
What it is
Metamerism explains why two colors can match under one light source but not under another, or why different spectral recipes can create the same perceived color.
Basics
- Human vision compresses complex spectra into cone responses.
- Two materials may match in daylight and differ under LED or fluorescent light.
- Metamerism is central to color matching, printing, textiles, and screens.
Notes for later expansion
- Later expansion should include practical examples from paint matching, clothing, and product photography.
