2023 Risograph Trilobe Synoptique Color Chart Calendar

This calendar is based on Trilobe Synoptique, a color system developed by Charles Lacouture in 1890. While the original color system utilized the three primary colors: red, blue, and yellow, we have chosen to explore various combinations of risograph inks overprinting together for our 2023 calendar. Each arch uses a varying opacity of ink. There is a chart included on the back side of the cover that can be used as a reference when viewing each of the calendar months.
