Amber Fen
Five stops tuned to sit together without fighting — #b32d00 ink anchors the set, #ffc7b9 opens it up, and #e65b38, #ff7f5e, #ff9b81 cross the middle in a tetradic arrangement. Amber Fen suits outdoor gear branding that reads in sun and shade. The darkest and lightest stops clear AA for large text.
