Opera palette
Copper Square
Five stops tuned to sit together without fighting — #006da5 ink anchors the set, #b3deff opens it up, and #0098e4, #44b5ff, #72c4ff cross the middle in a tetradic arrangement. Copper Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
