Do you see what I see?.

How do we know that colours really exist? Do we all see the same thing when we see what we think is red? At the Science Museum, Beau Lotto conducts an experiment on hundreds of people from different age groups and nationalities to attempt to assess if we all see colour in the same way. Russell Hill conducted experiments into the effects of the colour red - by studying red and blue in competitive sports he discovered that people wearing red were more likely to win in a competitive situation. But why? Does wearing red make the participant feel like a winner or does it make the judge perceive the red wearing participant as a winner? Further studies attempt to assess how different colours have powerful effects on our lives. But how do we mentally create colour in the first place? Anya Hurlbert demonstrates her research into colour constancy revealing that the eye doesn't simply see colour, the brain creates it. Anna Franklin of the Surrey Baby Lab describes how babies begin to see in colour - her research shows that colour and language are closely linked together. The Himba tribe from Namibia in Northern Africa describe colours in a very different way to us, partly because they have far less words than us, but partly because some of the colours in their world are not relevant to ours. The relationship between colour and emotion is also assessed and compared between old and young people.
