Chambray Heath
Five stops tuned to sit together without fighting — #ab3927 ink anchors the set, #ffc7bc opens it up, and #d86854, #f7846f, #ff9b88 cross the middle in a triadic arrangement. Chambray Heath suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
