Atlas Alley
Five stops tuned to sit together without fighting — #a04121 ink anchors the set, #ffc4b1 opens it up, and #cc6d4f, #eb896a, #f39e83 cross the middle in a tetradic arrangement. Atlas Alley suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA for large text.
