Abstract:

The visibility of bright and dark targets was compared when viewed through yellow filters whose excitation purity ranged from 0.06 to 0.98 as well as a neutral filter and whose total transmittances had been roughly equated. The visibility of large bright targets was enhanced by all the yellow filters but only to a very small degree. The visibility of the dark targets was also slightly enhanced, but these differences were not statistically significant. The color perception of both color normals and red-green dichromats was not affected by yellow filters whose excitation purity was less than 0.20.
