Butter Atelier
Five stops tuned to sit together without fighting — #92004f ink anchors the set, #ff9abd opens it up, and #c63877, #e65692, #ed73a1 cross the middle in a tetradic arrangement. Butter Atelier suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
