According to the BBC, a handful of small towns in the UK are installing pink lighting around shops, and other areas where teens hang out and cause trouble, because it makes acne and skin blemishes more visible.
Since teens are already incredibly self-conscious of the way they look, the last place they'll want to hang out is somewhere that's going to emphasize what makes them worried about their appearance.
The approach is not unlike the technique where speakers are used to play a high-pitched whine that only younger persons can hear, also deterring them from hanging around. But, neither approach is an actual solution to the problem. Unless these towns install pink bulbs everywhere, kids will always find a place to loiter. And it does nothing to deter the more attractive teens who aren't dealing with the unfortunate side effects of puberty. [BBC via Neatorama]
