Retro palette
Walnut Delta
Five stops tuned to sit together without fighting — #005e89 ink anchors the set, #8dd0fb opens it up, and #3588b8, #53a4d5, #70b3dd cross the middle in a tetradic arrangement. Walnut Delta suits outdoor gear branding that reads in sun and shade. The darkest and lightest stops clear AA for large text.
