Patrick Morrissey and Hanz Hancock interview painter Carol Robertson.

Robertson comments: "I’m presently dividing circles into multi-coloured sections which nevertheless still form an unbroken circle. The wonderful thing about a circle is that it always remains whole. For a couple of years I’ve been adding these divided rings running around the edge to create a sense of movement within the painting, so your eye starts to move around the circle in an almost kinetic way … I’m interested in rhythms and measured logic but I’m interested in subjective systems too. I want colour to read as light and disrupt the geometry."
