Join me as we discover how colour and light work together to shape our perception of the visual world around us. We’ll take a trip through the colours of the ‘visible electromagnetic spectrum’, as we reflect on our emotions we associate with the colours conveyed in culture and art. We’ll pause to delve into real-world examples and strange scenarios featuring goldfish, butchers, baseballers, underwear and more. Practical demonstrations show how coloured lighting can be used for helping health, tastier looking food, retailers swaying sales and making gambling more addictive. This talk is particularly useful for artists, crafters and small businesses, and comes with practical coloured light demonstrations for full effect.
