Abstract
The aim of this work is to evaluate the response of healthy subjects to the Farnsworth-Munsell 100 Hue color test using colored optical filters and without them under different illuminations. Thirty healthy subjects (range 20-27 years) performed this color test under simulated A, D65 and LED illuminants, without and with three different filters. Results indicate that LED could be a good alternative to perform Farnsworth Munsell 100 Hue color test. Colored filters modify color perception in specific spectral regions, it should be taken into account when a subject wears these filters.
