What Suisai is built on

In the app
Kubelka–Munk-based spectral pigment mixing, producing paint-like color mixtures rather than conventional RGB interpolation.

Lineage
Suisai began with Aquarelo, Giovanni Maria Cusaro's color tool and a fixture of my design workflow for many years.
When Aquarelo could no longer follow the Mac forward, I set out to make myself a replacement. Suisai soon became something quite different.
The starting point is acknowledged here with thanks.
