This collection was inspired from multiple paintings by Russian, abstract, and expressionism painter Wassily Kandinsky.  What I like best about his art is that he linked color to musical harmony by using pitch for the hue and volume for the saturation. 

"Color is the keyboard, the eyes are the harmonies, the soul is the piano with many strings.  The artist is the hand which plays, touching one key or another, to cause vibrations in the soul." 

- Kandinsky
