Lilac Lighthouse
Five stops tuned to sit together without fighting — #b20025 ink anchors the set, #ffbab6 opens it up, and #e04b51, #ff6b6c, #ff8a88 cross the middle in a tetradic arrangement. Lilac Lighthouse suits outdoor gear branding that reads in sun and shade. The darkest and lightest stops clear AA for large text.
