Monochrome palette
Polar Alley
A quiet five-stop monochrome arc with a confident middle — #3f6c00 carries the weight and #a9e27a carries the air, with #5c9a00, #77b734 and #8dc45d bridging in complementary formation. Built for national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
