Oat Square
Five stops tuned to sit together without fighting — #007469 ink anchors the set, #91e8db opens it up, and #2ea193, #51beaf, #74cbbe cross the middle in a analogous arrangement. Oat Square suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
