This test gives you an easy-to-administer but highly effective method for testing any individual's colour vision. Used by government and industry for over 40 years, the test consists of four trays containing a total of 85 removable reference caps (incremental hue variation) spanning the visible spectrum. Colour vision abnormalities and aptitude are detected by the ability of the subject to place the colour caps in order of hue.

The four trays are boxed in a brushed steel carrying case. The test must be administered under daylight conditions such as that provided by X-Rite SpectraLight or Judge II.
