Monochrome palette
Walnut Delta
Five stops tuned to sit together without fighting — #006f99 ink anchors the set, #a9e0ff opens it up, and #009bd4, #3bb8f2, #67c7f9 cross the middle in a complementary arrangement. Walnut Delta suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA for large text.
