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.

光谱过滤器选择，用于增加CVD受试者的色度多样性。

本文通过计算仿真分析了哪些光谱滤镜增加了正常色觉以及红绿色异常三色和双色的对象的可分辨颜色（NODC）的数量。滤光片是从一组滤光片中选择的，在这些滤光片中，我们对光谱透射率进行了建模。使用选定的滤光片，我们使用高光谱相机或光谱仪捕获的光谱反射率进行了仿真。我们还研究了这些滤镜对颜色坐标的影响。最后，我们模拟了两种广泛使用的色盲测试的结果：Ishihara和Farnsworth-Munsell 100 Hue（FM100）。在这些分析中，将所选过滤器与EnChroma和VINO公司的商业过滤器进行了比较。结果表明，所选过滤器的NODC增加并不重要。仿真结果表明，这些选择的滤镜都无法帮助色盲（CVD）受试者通过所研究的色盲测试集。使用标准比色法获得的这些结果支持以下假设：使用滤色片不会使CVD产生与正常观察者相似的感觉。
