Malty Abbey
Five stops tuned to sit together without fighting — #004978 ink anchors the set, #7ab9ef opens it up, and #2272ad, #418dca, #5e9dd1 cross the middle in a tetradic arrangement. Malty Abbey suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
