Ember Lighthouse
Five stops tuned to sit together without fighting — #8c3419 ink anchors the set, #fdac94 opens it up, and #b86046, #d67b60, #df9078 cross the middle in a split-complementary arrangement. Ember Lighthouse suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
