While most of the insects which have been studied can be generally described as having an ultraviolet (UV)-blue-green trichromacy, there are several different pigments and configurations which insects may have within their compound eye (Briscoe & Chittka 2001; Koshitaka et al.
For example, jumping spiders in the genus Habronattus have evolved a retinal filter in the AM eyes that increases their spectral sensitivities from UV-green dichromacy to UV-green-red trichromacy (Zurek et al.
There are three types of inherited CVD: monochromacy, dichromacy and anomalous trichromacy.
Further, the observer perceives color in terms of three color signals based on the trichromacy theory can be modeled by:
The dimensionality of color vision in carriers of anomalous trichromacy.
Trichromacy, in accordance with the Young-Helmholtz theory, is present at the receptor level and opponent processing, as proposed by Hering, is established in the inner retina.
Anomalous trichromacy (all three color cones are present, but the signals are transmitted to the brain abnormally).
There are also a number of misunderstandings in their application of trichromacy.
Establishing the trichromacy of vision also proved amenable to this
