Oat Lagoon
Five stops tuned to sit together without fighting — #00616b ink anchors the set, #7dd5e0 opens it up, and #008e9b, #38aab7, #60b8c3 cross the middle in a split-complementary arrangement. Oat Lagoon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
