Butter Library
Five stops tuned to sit together without fighting — #004f7c ink anchors the set, #77c0f9 opens it up, and #1078b7, #3894d5, #5aa3db cross the middle in a complementary arrangement. Butter Library suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
