The company X-Rite that owns the well known colour system Pantone have created an online test that can tell you your ‘Colour IQ’. Once completed it will give you a score between 0-99. Zero being perfect. Your score will also be given on a comparison scale based on your age and gender. My graphic designer friend who discovered the test got 7. I got 12 which I’m quite pleased with.
What did you get?
