Opera palette
Cobalt Granary
Five stops tuned to sit together without fighting — #004d7a ink anchors the set, #72bef9 opens it up, and #0076b7, #3292d5, #56a1da cross the middle in a tetradic arrangement. Cobalt Granary suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
