Opera palette
Lupine Boulevard
Five opera stops with room to breathe — #0067a2 grounds, #4191ce and #5eadec do the talking, #7bbdf3 softens, #abd8ff lifts. The tetradic bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
