The piece was installed seamlessly into the centre of a false wall constructed in front of an existing wall of the gallery. The aperture was at standing eye level.

The piece requires a dark space.

Colours cycle slowly through black, red, white, black, blue, white, black, etc. There is a differential in the timing of the two chambers, inner and outer (6 minutes and 8 minutes respectively) so that a gradual loss of synchronisation occurs, causing permutation of colour combinations to take place over time.

Total time of sequence: 24 minutes

Review: Helen Monaghan

There’s always something quite exciting about entering Sleeper. Leading exponent in light-based works, Adam Barker-Mill has created a new wall and within it he has cut out a circle. Mixing up a limited palette of colours, a circle of light illuminates the space. It ebbs and flows with a sequence of changing colours. Sometimes the circle looks flat, sometimes three-dimensional. As you stand transfixed, a multitude of images appears. The black and white combination is reminiscent of a cartoon eyeball. The green and red looks like an olive stuffed with a pepper. There’s a giant bowling ball and an eclipse. Intense purples merge into violet blues. Sumptuous reds evoke a spectacular sunset.

Lasting about 20 minutes, Colours is mesmerising, benefitting greatly from the windowless space. It is also very peaceful, a visual spectrum that takes you to another world. Simple in form, the piece is full of surprises. There is no apparent sequence – the colour combinations seem to be different every time. Barker-Mill has created a beautiful, ethereal installation and like his previous shows at Inverleith House in 1997 and as part of Northern Lights at the Fruitmarket Gallery, this is an experience not to be missed.
