Nebula palette
Crackling Grove
Five stops tuned to sit together without fighting — #004f68 ink anchors the set, #74c0e0 opens it up, and #007a9d, #3395ba, #57a4c2 cross the middle in a split-complementary arrangement. Crackling Grove suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
