Obsidian Square
Five stops tuned to sit together without fighting — #0b5ec9 ink anchors the set, #bdd7ff opens it up, and #448bf4, #71aaff, #8cbaff cross the middle in a monochromatic arrangement. Obsidian Square suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
