Manganese black. Yellow ocher. Vermilion. Ultramarine. These pigments sound delicious. Their names are so sharp and elegant, it’s as if the terms emote more meaning than just color. We can smell logwood, taste cochineal, touch mummy brown. There is just something (quite scientifically) alluring about a perfectly saturated glob of paint or an electric mound of powdered hues, especially when its name is so tantalizing.

The uniqueness of the names undoubtedly prompts those amongst us, who obsess over the various pink, purples and blues, to wonder where the terms come from. We learn the origin stories of famous paintings in art history course after art history course, but it’s rare to read about the birth of Madder red or mauve. How did the colors in Vincent van Gogh’s “Irises” or J.M.W. Turner’s “Modern Rome” come to be?

I never really thought about it but of course it’s true; these artists had to make their own paint and would of course create their own colors too.
