Oyster Cellar
Five stops tuned to sit together without fighting — #00648a ink anchors the set, #8cd6ff opens it up, and #1c8fc0, #43abde, #67bae5 cross the middle in a triadic arrangement. Oyster Cellar suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
