Sloe Pavilion
Five stops tuned to sit together without fighting — #0054a1 ink anchors the set, #9ac7ff opens it up, and #387ecf, #549aed, #70aaf2 cross the middle in a analogous arrangement. Sloe Pavilion suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
