Monochrome palette
Butter Atelier
Five stops tuned to sit together without fighting — #00555d ink anchors the set, #76c7d1 opens it up, and #00818d, #349da9, #59aab4 cross the middle in a triadic arrangement. Butter Atelier suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
