Frosty Foundry
Five stops tuned to sit together without fighting — #00535f ink anchors the set, #75c4d4 opens it up, and #007e90, #3499ac, #58a7b7 cross the middle in a triadic arrangement. Frosty Foundry suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
