There is a new quiz online that aims to test how well you can see different colours.
The eye test is devised by quiz site Playbuzz and shows a spectrum of varying different colours ranging from purple right through to a deep red.
You are then asked "How many colours can you see in the picture below?" before being given a list of four different options.
The answers include the following: Less than 20, 20-32, 32-39 and More than 39.
Each result gives you a different answer about what kind of eyesight you have.
If you spot less than 20 colours in the quiz, then you are a dichromat. This means, according to Playbuzz, that you probably have two cones in your eye.
