Colour Vision
Tracey Logan on how we create colour, via the biology of colour-blind eyes and women with colour superpowers. From January 2013.
In this series of five programmes, Tracey Logan dives into the world of colour, from biology to fashion.
Programme 1/5: Vision
We create all the colours we see around us. Cone cells in our eyes allow us to discriminate up to 10 million different hues. But not everyone's eyes contain the same type of cells, and this can change the range of colours we detect.
Tracey finds out what it's like to be colour blind and why there may be some women with superhuman colour vision, who can see more colours than the rest of us.
Presenter: Tracey Logan
Producer: Michelle Martin.
