I met a chap from an Advertising Agency today and was surprised when he offered me his business card. He didn’t offer me a single card; he offered me a selection from a fan of cards of different colour.

I chose the purple one and was then surprised when my PhD student told me she has chosen the same colour. A clever experiment in colour preference perhaps? Next time we meet I’ll have to ask him for the data. I hope he is keeping a record of which colour cards are proving most popular.

If you are interested in this you may like to have a look at my colour preference poll. After you take part in the poll (takes only a few seconds) you can see the results of the study so far.
