Steely Lagoon
Five stops tuned to sit together without fighting — #00556a ink anchors the set, #76c6e1 opens it up, and #00809e, #349cba, #5aaac4 cross the middle in a analogous arrangement. Steely Lagoon suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
