The test consists of identifying the various shapes formed by circles of different colours. Weâ??ve created a similar test for you to try! If you canâ??t answer the questions in our test, that may mean some colours are invisible to you. If thatâ??s the case, you may want to consult an ophthalmologist. The correct answers for this plate are: 7, 13, 16, 8, 12, and 9 (from left to right). Watch outâ??our test also contains letters and different shapes such as animals and objects. Good luck!
