Halcyon Lagoon
Five stops tuned to sit together without fighting — #007276 ink anchors the set, #86e7eb opens it up, and #00a0a5, #3cbdc1, #68cace cross the middle in a tetradic arrangement. Halcyon Lagoon suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
