Obsidian Mill
Five stops tuned to sit together without fighting — #822400 ink anchors the set, #ff9576 opens it up, and #c23a00, #e2582d, #e87350 cross the middle in a monochromatic arrangement. Obsidian Mill suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
