Cobalt Clearing
Five stops tuned to sit together without fighting — #005278 ink anchors the set, #81c2ec opens it up, and #297ba9, #4897c6, #65a5ce cross the middle in a split-complementary arrangement. Cobalt Clearing suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
