Ann Veronica Janssens medium is light. And mist. She uses the colours of light to create experiences where colours change as they intermingle at cross sections of colour. She recently exhibited at the Wellcome Trust with a piece titled yellowbluepink which I went to see.

Colours mixed through light are additive, like the colours you see on the computer monitor, and use red, green and blue (RGB). Yellowbluepink uses a mist of pink, yellow and blue, subtractive colours, which are used by printers (CMYK) to build colour. I was interested to see what would happen as the colours mixed together in the space. Yellowbluepink consisted of a coloured mist that you couldn’t quite see through. As you moved forwards the mist changed from red/pink, to yellow, to blue. Sense of direction becomes impaired and this seemed to get worse the darker the colour as the blue mist appeared more opaque. Other visitors shuffled around, arms out in front of them, trying to touch the walls. Where the colours merged the mist became red/orange and green/mauve which is not quite what you’d expect. This led me to reflect on colour creation, in particular additive and subtractive colour spectrums. There is current debate on the use of LED lights in theatre lighting, which have subtractive spectrums, whereas traditional Tungsten lighting, is additive.
