Conversion tables for simulating different types of color vision deficiency (CVD): Protanomaly, deutanomaly, tritanomaly.
protanomaly_cvd deutanomaly_cvd tritanomaly_cvd
Lists of 3x3 RGB-color transformation matrices for the various types of CVD. Each list contains 11 transformation matrices representing increasingly severe color vision deficiency.
Machado et al. (2009) have established a novel model, that allows to handle normal color
vision, anomalous trichromacy, and dichromacy in a unified way. They also provide conversion
formulas along with tables of certain constants that allow to simulate various types of
simulate_cvd for the corresponding simulation functions.
