What Suisai is built on
Suisai uses other people's work. This page names it, with the licence and the copyright line each project asks to be carried.
The app carries the same notices: About opens an Acknowledgements window holding every licence in full.
In the app
Kubelka–Munk spectral mixing. It's why blue and yellow make green on the Bench, rather than grey.

Lineage
Suisai began with Aquarelo, Giovanni Maria Cusaro's colour 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.
