Petrichor palette
Marble Lagoon
Five stops tuned to sit together without fighting — #007477 ink anchors the set, #8ce9eb opens it up, and #1da1a5, #46bec1, #6ecbce cross the middle in a split-complementary arrangement. Marble Lagoon suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
