The UK Sainsbury’s supermarket group has adopted higher impact traffic light labels designed to confront and change behaviour: red is bad, green is good.
Apparently, sales of products with mostly red lights have fallen by up to 25%, while some foods with more green lights – because of low fat, salt or sugar – have risen by up to 50%.
As a Sainsbury’s shopper myself, I have often found myself trying to become more colour coordinated, too.
