9 Online Tests You Can Take Now To Discover Everything About Yourself

8. Colour Perception

What we experience as colour is the result of different wavelengths of light hitting the cone cells in our eyes. There are three types of cone cell - short medium and long - and these typically correspond to red/green/blue colour vision that when combined allow us to see the whole visible spectrum.

If something in these cells goes wrong, however, it can cause a colour deficiency, preventing you from seeing a certain wavelength but, because colour perception is such a subjective experience, you might never know that you're not quite getting the full rainbow.

This test, based on the Farnsworth Munsell 100 Hue Test, challenges you ability to detect subtle differences between hues - it's much harder than it looks!
