Colourfield is an evolutionary ecosystem of colour. Colour agents try to exist in a simple universe by producing colours that are suited to their environment. This environment is determined by the other agents and the colours they produce. Entering into complex feedback cycles, Colourfield presents an evolving palette of shifting colours. Different configurations emerge based on the strategies the ecosystem discovers for co-existance and co-dependency. Harmonious configurations often remain stable for a short while, before eventually being replaced by new relations, better able to survive in the ever shifting environment.
