Do you have the eyes of a hawk, or are you as blind as a bat when it comes to seeing colours?
A new online test will tell you how good your colour vision is, then tell you what type of animal you're most like.
To find out how your eyesight ranks, all you have to do is look at a set of squares and highlight which one differs in colour.
The test, created by iGame, sounds easy enough, but a few rounds in and the odd boxes get a lot more difficult to see.
"Humans can distinguish colours when incoming light reacts with the cone cells in the retina of eye," the iGame website explains.
"There are three types of cone cells. Based on how they respond to light of wavelengths you will perceive the three basic colours; red, green and blue. The rest of the colours are perceived as a result of your brain combining the different cone cells.
"This is called tetrachromacy. A person like this can distinguish up to 100 million different colour tones."
