colourvision (version 2.1.0)

Colour Vision Models

Description

Colour vision models, colour spaces and colour thresholds. Provides flexibility to build user-defined colour vision models for n number of photoreceptor types. Includes Vorobyev & Osorio (1998) Receptor Noise Limited models , Chittka (1992) colour hexagon , and Endler & Mielke (2005) model . Models have been extended to accept any number of photoreceptor types.
