Oyster Cabin
Five stops tuned to sit together without fighting — #005e85 ink anchors the set, #80d1ff opens it up, and #0089bf, #37a5dd, #5fb4e3 cross the middle in a monochromatic arrangement. Oyster Cabin suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
