Vintage Cove
Five stops tuned to sit together without fighting — #9d2f00 ink anchors the set, #ffb69f opens it up, and #ca5e3c, #e97a57, #f09073 cross the middle in a tetradic arrangement. Vintage Cove suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
