Ettore Spalletti At the Henry Moore Institute, 74 The Headrow, Leeds, until 7 August At first sight, the HMI's three linked galleries are hung with square monochromes in blue and grey, but Ettore Spalletti's work is subtler the longer you look. Some panels, angled off the wall, are almost sculptural objects that inflect the space and don't just hang beside it. Edges bevelled more at one end than the other create spatial illusions of projection or recession when panels are combined. Spalletti applies the pigment in layers on top of plaster and then sands it so it no longer looks like a skin; you would think the panels had the same colour inside them.
A solitary pale-blue column stands in the high central room, and, when you circle it, all the works in the show become an entity - the installation unites the three rooms.
The exhibition catalogue costs £10.
