I don't believe I've ever spoken to Roy about painting or about his painting in particular, but I'm going to go out on a limb and say that he loves paint and he loves colour. That's certainly what I'm picking up on, anyway... Roy is also a poet, which may account for the poetic and dream-like quality of his paintings. They inhabit a different world from ours. From mine, anyway.
