Between 1933 and 1934, visionary artist and designer Sanzo Wada published his groundbreaking series "Haishoku Soukan" (配色辞典) – the original Dictionary of Color Combinations that established Japan's national color standards. These weren't merely design books; they were cultural artifacts that captured centuries of Japanese aesthetic wisdom in precise, reproducible formulas. Wada's meticulous documentation of hundreds of color relationships became the foundation of modern Japanese color theory, influencing everything from traditional kimono design to contemporary graphic arts.
