Tidal Plaza
Five stops tuned to sit together without fighting — #00627d ink anchors the set, #81d5f6 opens it up, and #118eb2, #3daacf, #63b8d8 cross the middle in a tetradic arrangement. Tidal Plaza suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
