The database

Oil paint colour charts, brand by brand

11 brand lines and 850 colours, the same database the Halftint engine mixes with. Each page lists the full range with pigment codes and tinting-strength flags, and shows a computed mixing gamut for the line’s tubes. Swatches are chart-derived and labelled approximate; the method page has the detail.

Your rack is probably in here

Pick your brand, tick the tubes you own, and the wheel shows what they can mix. Anything missing goes in as a custom tube by pigment code.
