Pigment identities and example transparency descriptions were referenced against Gamblin’s published Artist’s Oil Colors specifications (checked October 17, 2026). Recipes, screen colors and mixing predictions are our own uncalibrated estimates and do not reproduce measured Gamblin mixtures. The Mixing Room is not affiliated with or endorsed by Gamblin. Paint formulations and transparency vary by manufacturer; check your actual tube.

All screen colors, absorption/scattering inputs, tinting strengths and recipes are illustrative estimates. Titanium White has relative strength 1. Other strengths are fitted to estimated 1:4 white-tint lightness anchors, with a shared dark-paint correction of 0.070. Mixing uses 31 estimated spectral bands; neither these spectra nor the reference tints are physical measurements. Thin-film previews show an estimated layer over a light ground, not a measured glaze or solvent recipe. Parts mean approximate equal volumes of paint. Check a small mixture before making a pile.

This example palette uses PBr7 Burnt Sienna and a two-pigment Sap Green (PY83 + PB15:2). Their transparency labels describe the referenced formulations, not every paint sold under those names. These material differences matter even when two opaque screen colors look similar.
