Halcyon Foundry
Five stops tuned to sit together without fighting — #00487f ink anchors the set, #7bb8f6 opens it up, and #2570b4, #438bd2, #5f9bd7 cross the middle in a tetradic arrangement. Halcyon Foundry suits coffee bags and cafe menus that need appetite on crowded shelves. The darkest and lightest stops clear AA for large text.
