Join researchers from the Soton Colour Lab of the School of Psychology at the University of Southampton for the Gummy Bear Colour Hero to test whether your brain can beat physics. Under special light, participants race to sort gummy bears by colour and earn a place on the Hall of Fame. When the white light comes back on, it will not only help seeing the Gummy Bear colours but also illuminate how colour perception works. See you at Science & Engineering Day 2026.
