An electronic company were testing for a new boom box they hoped to start selling. Their research included focus groups where they showed the two colour options, yellow and black. The participants were in agreement that yellow was the best colour because it is a vibrant and energetic colour. At the end of the focus group they were each allowed to take a boom box home, and could choose yellow or black. They all chose black.
