PURPOSE: To use a theoretical model of the observer on the Farnsworth-Munsell 100-hue test to estimate the magnitude of random variation in 100-Hue test error scores. METHODS: The model was based upon classical signal detection theory. Results from the model were obtained by computer simulation. RESULTS: There is a fairly regular relationship between mean test scores over many tests and the standard deviation of those scores. This relationship is for practical purposes unaffected by polarity in the observer's hue discrimination and by changes in the detailed assumptions of the model. CONCLUSION: The model provides a flexible tool for further theoretical research into the 100-hue test.
