Sienna Square
Five stops tuned to sit together without fighting — #006691 ink anchors the set, #98d8ff opens it up, and #3e90bd, #5bacda, #79bbe3 cross the middle in a analogous arrangement. Sienna Square suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
