Wall-brightener supplier Dulux has launched a fundraising scheme called Own A Colour alongside UNICEF, which gives charity-minded people the chance to pick one of 16.7m colours and give it a unique name.
All you're obliged to do is pop off to the site and click around the slick, triangle-based interface until you see a colour that speaks to you on some base level. Then you can give it a name, attach a heart-warming story to it (optional), donate some money (£1 is the minimum) and there you go.
Blue is now called "Yellow" and you can feel happy for at least a week because you donated some money to UNICEF. [Own A Colour]
