In our eyes are little structures called Cones and Rods. The rods help us see better in the dark while the cones help us see better in the day and are especially good at seeing color (you may have noticed that in the dark the world is less chromatic, that is because the cones are not as activated). Seeing color is a good trait for our species, used in the past to detect predators, find fruits and berries and avoid poisonous and venomous flora and fauna that would otherwise kill us. This vision test will see how well you see color, you may even see better than average people, as some of us have hyper-chromatic vision!
