Tawny Lagoon
Five stops tuned to sit together without fighting — #7c0000 ink anchors the set, #ee8b7c opens it up, and #a93c30, #c8584a, #cf6f61 cross the middle in a analogous arrangement. Tawny Lagoon suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA as a text pair.
