Oat Courtyard
Five stops tuned to sit together without fighting — #004a7c ink anchors the set, #70bafc opens it up, and #0072bb, #308ed9, #549dde cross the middle in a tetradic arrangement. Oat Courtyard suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
