Purpose: : To investigate the influence of a circular and a linear arrangement on the results of the hue arrangement test Roth 28–hue (E) desaturated.

Methods: : In a cross–over study, 19 healthy subjects (m:f=6:13; mean age 32± 11 years) started color vision testing with the circular test first, followed by the linear test, while another 19 healthy subjects (m:f=7:12; mean age=29±10 years) did the tests in a reverse sequence. Color vision, examined by the hue arrangement test, Roth 28–hue (E) desaturated, was measured monoculary under standard conditions in both eyes. The background was a black cardboard; illumination was provided by fluorescent light sources with a balanced spectral distribution and a color–rendering index of 93 (Osram L36W/12 LDL).

Results: : No statistical significant difference could be measured in the error scores and the color axis between the circular and the linear arrangement. However, 81% of the subjects in each group claimed to prefer the circular arrangement.

Conclusions: : The preference for the circular arrangement of the caps is perhaps a hint for the subconscious idea of the circle–nature of colors. Especially in patients with acquired color–vision disturbances with several follow–ups as well as in children and elderly, the more comfortable circular test arrangement should be considered.
