Seafoam Reef
Five stops tuned to sit together without fighting — #a33b2e ink anchors the set, #ffc2b8 opens it up, and #d06859, #ef8474, #f79a8b cross the middle in a analogous arrangement. Seafoam Reef suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA for large text.
