I know, it's sort of a fad thing, but this test is sort of an interesting exercise to get a sense of how attuned your eyes are to spotting color and brightness. However if you try this, I recommend not taking it in the spirit of trying to score as high as possible, but more in the spirit of just knowing how well attuned your eyes are. Training your eyes to see color and contrast and brightness is a skill that can be trained to some degree. Knowing your current ability to spot color gives you a sense of how much room for improvement you have.

So give it a try! Kuku Kube
