Vale Oasis
Five stops tuned to sit together without fighting — #7a002b ink anchors the set, #ee8796 opens it up, and #a93750, #c85369, #cf6b7b cross the middle in a tetradic arrangement. Vale Oasis suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
