What's YOUR colour IQ? Take the test to see how your perception of different shades compares to other people your age

Anyone who's ever stared in desperation at a paint colour chart will know that telling shades apart is not always the easiest task. Due to our biological differences, some people seem to have no trouble separating the subtlest of tones, while others find it tricky to find a matching pair of socks. If you've ever wondered where you fall on this colour spectrum, a new test will reveal how you stack up against your peers. So, what's your colour IQ? Take the test at this link to find out. The test, created by X-rite Pantone, is a simplified version of something called the Farnsworth Munsell 100 Hue Test which was developed in the 1940s by a scientist called Dean Farnsworth.
