ABSTRACT Historically, there has been little quantitative rationale for the prescription of colored filters for color deficients. A formal prediction of the effects of any filter on dichromat luminance and chromatic discrimination is presented; these predictions were generated by using colorimetric concepts and related derived formulas to create four interactive computer‐graphic tools. In addition to predicting performance of presently available commercial filters, such tools can be used to describe, classify, and even design new filters.
