Definition of trichromatic in US English:



  • 1Having or using three colors.

    • ‘The general principle underlying the design of visual trichromatic colorimeters. may be briefly summarized as follows.’
    • ‘An important theory was put forward by Young in the 18th century and was developed by Helmholz to give the trichromatic scheme which states that there are three fundamental colours.’
    1. 1.1 Having normal color vision, which is sensitive to all three primary colors.
      • ‘People with trichromatic color vision see not only four primary colors (blue, green, yellow, and red) but also various intermediate colors between them.’
      • ‘Primates, including humans, have three cones and can thus distinguish three of the primary color phases, giving us trichromatic vision, or high color resolution.’
      • ‘The human eye is trichromatic, as our color vision involves three distinct classes of cones.’
      • ‘The nocturnal origins of primates imposed constraints on certain sensory systems, namely trichromatic vision.’
      • ‘Similarly, we may have preferences for certain colors based on the primate trichromatic color visual system.’
      • ‘Accordingly, the successful acquisition of fruits (or fruits of particular colors) cannot be strongly tied to the evolution of routine trichromatic vision.’
      • ‘Between 30 million and 35 million years ago, however, our primate ancestors began to develop the trichromatic color sensitivity that humans, apes, and Old World monkeys possess today.’
      • ‘Many species - including the trichromatic honeybee - have a kind of photoreceptor sensitive to the near-ultraviolet, outside the visible spectrum.’
      • ‘Theoretical modeling of fruit spectra into the trichromatic color space of catarrhine primates yielded similar results.’
      • ‘None of today's New World monkeys has trichromatic color vision - except for the howler monkey.’
      • ‘Here I show that softening texture also characterizes the fruit ripening process, and that color is of ambiguous importance to primates possessing trichromatic vision.’
      • ‘Why would the only monkey in South America to evolve trichromatic vision be the one that eats the least amount of fruit?’
