Madder Brown, named after the old dye root, is a deep rusty maroon, and it gives Lemon Yellow and the pale mint Turquoise Green something solid to push against. The result is cheerful yet sturdy, like a hand-painted folk pottery bowl. With an 8.0 contrast ratio, Madder Brown text on the yellow or mint is very readable, making it a good choice for a children's publisher, a grocery brand or posters.
