Different colours can affect us in many different ways, according to Verity Allen. In her new series ' Colour me Healthy', Verity looks at the ways that colours can influence how hard we work and the choices we make.

" Our toothpaste is always white or blue or maybe red. It's never green. For some reason we consider green products as being a bit unacceptable. It's the same for businesses. We respect a company writing its name in blue or black, but we don't respect one that uses pink or orange. People designing new products can use these ideas to influence what we buy."

She meets people who work in all aspects  of the colour industry, from people designing food packets , to people naming the colours of lipsticks . Some of the people she meets clearly have very little scientific knowledge to support their ideas, such as the American " Colour Doctor" who believes that serious diseases can be treated by the use of coloured lights. However, she also interviews real scientists who are studying the effects of green and red lights on mice, with some surprising results. In a word, it's an interesting show, and anyone who watches it will probably find out something new.
