The idea behind this is so simple and brilliant - your average computer/phone/ipad can display 16.7 million colours. Unicef wants you name each colour by donating at least 1 pound for the ownership of a colour, which goes directly to help transform children's lives.
I've already picked one (spent too long browsing through the different variations of salmon pink!) and named it 'Blushing Really Bright'. It's a beautiful, simple and interactive website - you'll be excited if you're a designer!
I think I'm going to buy more now..check it out here.
