The works in this exhibition are captivating in their luminosity and interplay of colours; their arrangement in space activates perception and heightens sensitivity to subtle nuances. The metallic grey of aluminium and silver suddenly takes on different shades when reflected in the light. Glass, in the form of a dark block of obsidian, seems not only to reflect light but also to absorb it. As a support for reverse glass paintings, it makes colours appear more intense. But the exhibition also raises questions that may lead to some unexpected insights: do colours appear more luminous when applied over a larger surface? Or do fine lines suffice? Can colour create spatial depth? Or at least the illusion of it?
