Glassy Brook
Five stops tuned to sit together without fighting — #832300 ink anchors the set, #ff9677 opens it up, and #c33a02, #e3582e, #e97351 cross the middle in a tetradic arrangement. Glassy Brook suits restaurant branding that works on signage and receipts alike. The darkest and lightest stops clear AA for large text.
