Tracey Logan dives into the world of colour, from biology to fashion. 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. Series of five programmes. Producer: Michelle Martin First broadcast on 麻豆社 Radio 4 in January 2013.
