Granite Delta
Five stops tuned to sit together without fighting — #a42f16 ink anchors the set, #ffbcac opens it up, and #d15f47, #f07b62, #f7927c cross the middle in a split-complementary arrangement. Granite Delta suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
