Harbor Boulevard
Five stops tuned to sit together without fighting — #9c3529 ink anchors the set, #ffb8ac opens it up, and #c86254, #e77e6e, #ef9485 cross the middle in a triadic arrangement. Harbor Boulevard suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
