Acid palette
Pastoral Foundry
Dark anchor, working middle, light release: #004e49, #007a73, #32958e, #55a29b, #72bfb7 form a monochromatic acid set with somewhere to stand at every lightness. Made for event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
