Oat Plaza
Five stops tuned to sit together without fighting — #005771 ink anchors the set, #78c9ea opens it up, and #0082a7, #359ec4, #5baccd cross the middle in a monochromatic arrangement. Oat Plaza suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
