How to Mix Vermilion in Oil

Quick answer

To mix vermilion (#D93A20) in oil, use 4 parts Yellow Ochre to 3 parts Cadmium Red. Chromilla's model predicts a 97% dry match against the target, scored against its own color model, not a measured paint-out. Chromilla is a web-based paint color mixer that turns any color, from a photo, the camera or a hex code, into exact paint-tube ratios for acrylic, oil and watercolor, using Kubelka-Munk pigment mixing and aiming at the color after it dries.
