Nebula palette
Walnut Depot
Five stops tuned to sit together without fighting — #006f5e ink anchors the set, #83e5ce opens it up, and #009e86, #3bbba1, #65c7b1 cross the middle in a tetradic arrangement. Walnut Depot suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
