abstract = {This paper analyzes, through computational simulations, which spectral filters increase
the number of discernible colors (NODC) of subjects with normal color vision, as well as red–green
anomalous trichromats and dichromats. The filters are selected from a set of filters in which we have
modeled spectral transmittances. With the selected filters we have carried out simulations performed
using the spectral reflectances captured either by a hyperspectral camera or by a spectrometer. We
have also studied the effects of these filters on color coordinates. Finally, we have simulated the results
of two widely used color blindness tests: Ishihara and Farnsworth–Munsell 100 Hue (FM100). In
these analyses the selected filters are compared with the commercial filters from EnChroma and VINO
companies. The results show that the increase in NODC with the selected filters is not relevant. The
simulation results show that none of these chosen filters help color vision deficiency (CVD) subjects
to pass the set of color blindness tests studied. These results obtained using standard colorimetry
support the hypothesis that the use of color filters does not cause CVDs to have a perception similar
to that of a normal observer.},
