Colour by Numbers was a light installation in the Tower of Perdigones, Seville, Spain (map). Everyone could change the colours in the tower with their mobile phone, just like with a remote control. Colour by Numbers was part of the International Biennial of Contemporary Art of Seville, Biacs3. The light installation was previously installed at Telefonplan, Stockholm, Sweden (read more here).

 

 

1. Call +34 656 83 24 56 and follow the instructions to colour the tower. The call costs like a normal phone call and has a time limit of five minutes, so that more people can get through.

2. Select the floors you wish to colour by pressing the digits 1 to 9, 8 being the topmost floor, and 1 the bottommost. 9 will select all floors. Finish by pressing #. At any time, you can press * to go back and change your selection of floors.

 

3. Colour the selected floors. Any colour can be created by mixing red, green and blue. The digits 1 to 3, the top row of numbers on your telephone, control red. 1 gives less red, 3 gives more. The middle row controls green. 4 gives less green, and 6 gives more. The bottom row controls blue. 7 gives less blue, and 9 gives more. When you have finished colouring, you can press * to go back and select other floors.

 

Colour by Numbers is switched off during the daytime.
