Cobalt Cellar
Five stops tuned to sit together without fighting — #214fa3 ink anchors the set, #a1c4ff opens it up, and #4b7acd, #6596eb, #7ca7f0 cross the middle in a monochromatic arrangement. Cobalt Cellar suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
