Colour vision involves the physical world, the eye and the brain. The role of each will be explained during the lecture. In fact many scientists believe that the colours we see exist only exist in our brains.
The lecture will include several demonstrations in order to understand how we discriminate between colours. Some demonstrations will include audience participation and some have unexplained and surprising results. These include the generation of colour without using pigments.
Instructions on how to reproduce some of the experiments at home will be given, together with internet addresses where to get more information and relevant software.
