Effect of digitally generated colored filters on Farnsworth-Munsell 100 hue test by red-green color vision-deficient observers


 In this study, the effects of four different digitally generated colored filters on the Farnsworth-Munsell 100 hue test (100-hue test) are analyzed by red-green color-vision deficient (CVD) observers. We digitally simulate the colored filters based on the spectral transmittance of
 four colored filters, which have been used previously. Five red-green CVD observers are subjected to the 100-hue test on a monitor under nine filter conditions, which comprise one condition without filter and eight conditions with filters. The results suggest that a colored filter that transmits
 long wavelengths and absorbs medium wavelengths may improve the color discrimination performance of protans and deutans.
