Monochrome palette
Sandy Foundry
Five stops tuned to sit together without fighting — #004a6a ink anchors the set, #70b9e4 opens it up, and #0073a2, #318ebf, #549dc6 cross the middle in a monochromatic arrangement. Sandy Foundry suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
