Cobalt Depot
Five stops tuned to sit together without fighting — #0054a4 ink anchors the set, #9cc8ff opens it up, and #0d7ce8, #439aff, #66abff cross the middle in a tetradic arrangement. Cobalt Depot suits yoga studio schedules pinned to a corkboard. The darkest and lightest stops clear AA for large text.
