Blue Hour palette
Porcelain Crater
Five stops tuned to sit together without fighting — #004f77 ink anchors the set, #7dbfed opens it up, and #2378ab, #4393c8, #61a2d0 cross the middle in a tetradic arrangement. Porcelain Crater suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
