Oyster Manor
Five stops tuned to sit together without fighting — #3a57a6 ink anchors the set, #b6cdff opens it up, and #6282d0, #7c9eee, #91aff4 cross the middle in a analogous arrangement. Oyster Manor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
