Mercurial Prairie
Five stops tuned to sit together without fighting — #6f2800 ink anchors the set, #f09168 opens it up, and #ab4300, #ca5f2b, #d1754c cross the middle in a tetradic arrangement. Mercurial Prairie suits outdoor gear branding that reads in sun and shade. The darkest and lightest stops clear AA as a text pair.
