Opera palette
Butter Alley
A quiet five-stop opera arc with a confident middle — #00669f carries the weight and #a8d8ff carries the air, with #0091de, #39aefd and #66bdff bridging in analogous formation. Built for museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
