Amber Reef
Five stops tuned to sit together without fighting — #005d94 ink anchors the set, #96cfff opens it up, and #0587d3, #38a3f1, #5fb3f6 cross the middle in a tetradic arrangement. Amber Reef suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
