Ceiling and a floor for The Swedish Pavillion at the World Exhibition in Seville. The theme was ’the inspiration of light’. The project explored the interaction between coloured light and surface colours. The ceiling was painted in a pattern that consisted of the physical basic colours red – green – blue as well as black and white. Circle bows of cyan and yellow cut the pattern. The circle bows have their centre point about 60 meters outside the building. The ceiling could be lit with a spotlight and dichromatic filters in red — green — blue with the same spectral curves as the painted colours.

With red light, all the green coloured become black. In green light, all the red surfaces become black, in blue light the yellow bow becomes like a black shadow etc. By changing the coloured lighting totally different patterns appeared.

I created 20 different images, programmed into a computer, that repeated in a six-minute sequence from nightfall until morning throughout the six months of the exhibition.

The building is now situated in Grythyttan and houses The Restaurant Academy.
