Oaken Reef
Five stops tuned to sit together without fighting — #4a2897 ink anchors the set, #b2a2ff opens it up, and #6f56c1, #8972df, #9785e3 cross the middle in a tetradic arrangement. Oaken Reef suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
