Exploding with color, information and inspiration, "7 Color Contrasts with Risography" is a vibrant guide to the power of contrast in visual communication as explored through the medium of RISO printing. The new edition includes a fold out chart that maps the hue and saturation of 26 riso colors, a color bias wheel that translates the logic of a painter’s palette to risography, and a separate color index that draws attention to the inherent lightness of riso colors printed at their full saturation. The first edition of 7 Color Contrast with Risography is archived at the Harvard Houghton Library and The Cooper Hewitt. It was featured by Printed Matter at New York Art Book Fair in 2024.
