Farnsworth Munsell 100 Hue Test

The Farnsworth-Munsell 100 Hue Test itself is used to separate persons with normal colour vision into classes of superior, average and low colour discrimination and to measure the zones of colour confusion of colour defective people.

Under simulated daylight conditions, each tray is opened separately, and the discs are spread out on a table randomly. The subject is then asked, using the stable pilot discs for reference, to align the 85 colour disks in order of a colour scale (hue) order. This test provides a good indication of an individual’s accuracy in judging small differences in colour.

Hue discrimination ability is estimated from the total error score and the type of colour deficiency is determined from a graphical representation of the results. Colour vision anomalies and colour aptitude are detected by the ability of tester to place colour caps in hue order.

The FM100 Hue Test is an easy-to-administer test and a highly effective method for measuring an individual's colour vision. Used by industry for over 40 years, the test is used to evaluate and rank colour acuity. This portable test equipment analyzes how accurately you see colour. The easy-to-use scoring software indicates where you have a colour vision deficiency such as colour blindness.
