Seaside Ridge
Five stops tuned to sit together without fighting — #923b1d ink anchors the set, #ffb59d opens it up, and #be674a, #dc8265, #e5977d cross the middle in a tetradic arrangement. Seaside Ridge suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
