Nestle’s new television adverts for Smarties are a cross between grown-up Teletubbies in head-to-toe lycra jumpsuits and the parable of the prodigal son. You’ve probably caught a glimpse of their idyllic, pastoral scene being abruptly disrupted by the appearance of Blue Smartie on the ridgeline. His former friends flee to the safety of their tubular home, dispatching Yellow to get rid of the unwelcome intruder. All is well though, because Blue is now free of artificial colours; no longer a pariah, he can rejoin the community. The Smarties rainbow is complete again.
How sweet. But, one wonders, why were the old colours dropped? Why has it taken so long to replace blue? And perhaps most importantly, what has it been replaced with?
