“All colours on the palette are beautiful.  And between adjacent colours harmony exists.  At the completion of the work one should observe how the colours have randomly blended on the palette.  Sometimes these random mixtures are so harmonious that it is impossible to forget the impression that they make.  Often this accidental harmony is contrary to all expectations:  the palette is a part of nature.  If a certain mixture is particularly harmonious one should immediately try to enhance it.  Even if this is usually futile, it helps one to understand why that harmony disappeared.”

– Wassily Kandinsky, The Palette
