Monochrome palette
Tranquil Library
Five stops tuned to sit together without fighting — #005459 ink anchors the set, #76c5cb opens it up, and #008087, #349ca2, #59a9af cross the middle in a triadic arrangement. Tranquil Library suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
