I'm not sure what to make of the Guggenheim Colors by Fine Paints of Europe. It looks like a finely tuned color fandeck that may provide you with some inspiration. But what to do with 'the perfect wall colors to complement the celebrated collection of modern art', if you don't have the same walls, nor the same collection? The Guggenheim Museum, a Frank Lloyd Wright masterpiece, is a very specific space, with very specific light and shape. There's just no way that the same colors will yield the same result in your living room.
Yet, if you cut through the smoke and mirrors, this may be a nice tool for inspiration. Just don't expect these colors to do exactly the same for you as they did for the Guggenheim.
