Physical Paint Realism for the Modern Digital Age
For decades, computer screens have forced creators to work with additive RGB light, which turns mixed paints into dull, murky grey. PigmentLab was born to restore authentic physical light absorption and classical Bauhaus color harmony to the web.
The Problem with Standard Digital Color Tools
Why do digital color pickers feel so artificial compared to real oils, gouache, and acrylics?
Linear RGB Math (Light Emitted)
Standard computer monitors emit photons. When you mix Blue (0, 0, 255) and Yellow (255, 255, 0) in traditional software, the mathematical average lands on dull grey (#808080).
Kubelka-Munk Spectral Absorption
Physical pigments absorb specific wavelengths of light. PigmentLab simulates this subtractive behavior, producing luminous emerald green when blending Blue and Yellow.
