Luminous Kiln
Five stops tuned to sit together without fighting — #8c3a00 ink anchors the set, #fdb18c opens it up, and #b8653a, #d68055, #df9470 cross the middle in a analogous arrangement. Luminous Kiln suits bakery boxes stamped with a single ink color. The darkest and lightest stops clear AA for large text.
