ARC-supported researchers from The University of Queensland have developed a more efficient and accurate method for studying colour vision in animals.   

Based on the Ishihara colour blindness test, the test used on humans by optometrists, the new method uses a ‘colour spot’ method, training triggerfish to find an odd-coloured spot in a field of spots and to peck it for a food reward. Unlike traditional methods, this test allows researchers to test a variety of different colours and has the potential to be applied across a variety of animal species.
