One of the themes in our exhibition 'Vincent. The Van Gogh Museum in the Hermitage Amsterdam' is 'The effect of colour'. A quote by Van Gogh about colour: "COLOUR EXPRESSES SOMETHING IN ITSELF. One can’t do without it; one must make use of it. What looks beautiful, really beautiful — is also right." (Vincent van Gogh, Nuenen, 28 October 1885) Exhibition info: www.vangoghmuseum.com Image: Vincent van Gogh, Gauguin's chair, 1888, Van Gogh Museum, Amsterdam (Vincent van Gogh Foundation).
