Web2 apr. 1992 · The absorption spectra of the human cone pigments have been sought for over a century 2 using techniques such as psychophysical colour matching 3, reflection densitometry 4, electroretinography... WebHuman color vision is normally trichromatic, and requires at least 3 cone photopigments: 1 from each of 3 well-separated spectral classes. The 3 classes of pigment differ in their relative spectral sensitivities, and are commonly referred to as the blue, green, and red cone pigments. However, using color names for the photopigments can be ...
