...like this range. There is not a bright yellow to make greens, or a true red, or pink to make purples. It will force some interpretation. It is also full of granulating and largely non-transparent colours.
I mixed Quin Gold with Goethite to create a brighter mixing granulating earth yellow. I mixed Burnt Sienna with Transparent Red Oxide to create a brighter Burnt Sienna. I chose Sodalite Genuine rather than Jane's Gery as a dark to add even more granulation, though it is also better for colour harmony since I don't have ultramarine in the palette (!)
It is based around a primary triad of Indian red, Cerulean chromium and the earthy yellow so it's a very earthy palette. Without Ultramarine, my basic blue, it'll be really interesting to paint with, especially wet into wet with a large brush.
