trichromatic

This research suggests the species has trichromatic vision, like humans.

Platyrrhines, on the other hand, are trichromatic in a few cases only.

For humans, three primary colors are usually used, since human color vision is trichromatic.

However, this appears to be an adaptation to low light levels rather than representing true trichromatic vision.

Thus trichromatic color vision is accomplished by using combinations of cell responses.

This is the mechanism that allows trichromatic color vision in humans and some other animals.

This suggests that this species may have colour vision - perhaps trichromatic.

After five months of gene therapy treatment, the monkeys began to acquire trichromatic color vision.

Combining the same three classes is one way to make trichromatic systems in TV and computer screens.

To find their prey, salamanders use trichromatic color vision in the ultraviolet range.

The Trichromatic theory was proposed in 1802 by Thomas Young.

The moth therefore has the cellular prerequisites for trichromatic colour vision.

There is even an interactive routine to show the effects of trichromatic mixing of colors.

Two complementary theories of color vision are the trichromatic theory and the opponent process theory.

The sensitive trichromatic color vision of a salamander.

Metameric matches made between two light sources provide the trichromatic basis of colorimetry.

This provided the first biological demonstration in support of the Young-Helmholz trichromatic theory.

The trichromatic theory discussed above is strictly true when the visual system is in a fixed state of adaptation.

Honey- and bumblebees have trichromatic color vision, which is insensitive to red but sensitive to ultraviolet.

Physiological evidence for trichromatic theory was later given by Gunnar Svaetichin (1956).

In 1801 Thomas Young proposed his trichromatic theory, based on the observation that any color could be matched with a combination of three lights.

Humans being trichromatic, the retina contains three types of color receptor cells, or cones.

The three alleles seem to be equally common, leading to one-third of females being dichromatic while two-thirds are trichromatic.

Some pollinators may use tetrachromatic color vision to increase and maintain a higher foraging success rate over their trichromatic competitors.

Trichromatic lighting provides much higher light output for a given amount of electrical energy than does incandescent lighting.
