Earthen Reef
Five stops tuned to sit together without fighting — #007172 ink anchors the set, #85e6e6 opens it up, and #009fa0, #3cbcbc, #67c9c9 cross the middle in a tetradic arrangement. Earthen Reef suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
