The works in Callum Innes’ Untitled Lamp Black series appear at first to be two colours. Untitled Lamp Black / Quinacridone Gold is in fact composed of layers of colour; in the first instance the entire canvas is painted black - turpentine is then repeatedly applied by brush to remove paint from part of the surface. Innes washes away or as he has described it, “unpaints”, leaving all but the faintest vestigial traces of pigment. The remaining black part of the canvas is then over painted with another colour, resulting in an effect that is both rich and luminous. A play between the additive and subtractive process, making and unmaking, and the sheer enjoyment of paint underlies this very sophisticated body of work.
