Colour constancy illusions and painting

In this video I’ll be taking a fresh look at colour constancy illusions,  what they do and don’t tell us about visual perception and how they illustrate a basic practical difficulty involved in painting appearances. Popular illusions published by neuroscientists Dale Purves and Beau Lotto show something very different to what Purves and Lotto thought they show. The lecture was first presented at the Colour Society of Australia Melbourne 2018 Conference, PERCEPTION & COLOUR.
