Color vision models: Some simulations, a general n‐dimensional model, and the colourvision R package

Abstract The development of color vision models has allowed the appraisal of color vision independent of the human experience. These models are now widely used in ecology and evolution studies. However, in common scenarios of color measurement, color vision models may generate spurious results. Here...
