Opera palette
River Heath
Five opera stops with room to breathe — #004c6f grounds, #0075a9 and #3190c6 do the talking, #559fcd softens, #71bceb lifts. The triadic bones keep it coherent across flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
