Abstract The scoring artefact in the Farnsworth‐Munsell 100‐Hue test, arising from the grouping of the caps into four boxes, was investigated. The traditional method of scoring performed with the numbers of the anchor caps disregarded and the alternative scoring performed with the numbers of the anchor caps employed, were compared. For the traditional method of scoring, we revealed an increase of the error score of the outside (end‐box) caps when the total error score was above 240. On the contrary for scoring performed with the numbers of the anchor caps employed, the difference between the error score of the outside caps and the average error per cap is not significant. To mitigate the end‐box artefact and to improve the reliability of the Farnsworth‐Munsell 100‐Hue test, corrections to the traditional method of scoring are proposed.
