Okay - so it's an old one... but it springs to mind every time I spot that peculiar brown Andrex variety loitering in Tesco. Now we all know that colours play a big part in communications (red outpulls yellow, which outpulls gold, which outpulls black... that kind of thing), added to which I have some form in the paper products business, albeit now a little dated. There was a time when I sat on a research budget that would make most marketers' eyes water (there's an image!). In those pre-Ikea halcyon days of lilac and avocado we knew what was taboo... in the loo. And there was one colour above all others that should not be allowed within a mile of the pack (and frankly it didn't take paid research to work this out). Maybe mores have changed - as tastes do - but somehow intuition feels more permanent, and I'm struggling to be convinced that brown is the new beige. Ring a bell? Dung.
