Monochrome palette
Nightfall Square
A quiet five-stop monochrome arc with a confident middle — #004657 carries the weight and #6eb5cd carries the air, with #00708a, #308ba6 and #5299b0 bridging in tetradic formation. Built for wellness apps where the interface must feel calm, not clinical. The darkest and lightest stops clear AA as a text pair.
