Based on the original 6-volume work of Sanzo Wada from the 1930s, A Dictionary of Colour Combinations offers 348 colour combinations, focussing on the importance of colour and laying the foundation for contemporary colour research.

Following on that enduring bestseller, 'A Dictionary of Color Combinations' Vol. 2 brings back two more works by Wada published in 1935–1936 and 1938, respectively.
