Opal Alley
Five stops tuned to sit together without fighting — #7d3700 ink anchors the set, #f8a578 opens it up, and #b3591e, #d1743d, #d9895c cross the middle in a triadic arrangement. Opal Alley suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
