The example provided by the uses of trichromacy is thus also an excellent model — within this larger object, color — of eighteenth-century interaction between practice and theory. ❋ Unknown (2006)
It is called trichromacy, because it depends on three types of light - activated pigments in the retina of the eye. ❋ Unknown (2009)
This property of human vision, called trichromacy, arises because the retina the layer of nerve cells in the eye that captures light and transmits visual information to the brain uses only three types of light-absorbing pigments for color vision. ❋ Unknown (2009)
This is the physiological basis for what is called “trichromacy,” that is, the three-color basis for human color vision. ❋ James L. Kugel (2011)
Small bodies associate to make a new color. reference For Le Blon, Newton's description affirmed practical understanding of color mixing and trichromacy. ❋ Unknown (2006)
The result casts some typical ideas of his time, notably the emphasis on trichromacy and the description of vision, into a new vocabulary without accompanying conceptual changes. ❋ Unknown (2006)
Practical realities underlying the ideal of trichromacy and the creation of black and white limited the use of practices in the explanation of theories. ❋ Unknown (2006)
Some eighteenth-century recipes to create black for textiles call for successive dyeings in blue, red, and yellow baths. 13 One rationale for the habit should be obvious; the choice of these three colors creates a link to the concept of trichromacy, but the economic implications of the recommendation are considerably more complicated. ❋ Unknown (2006)
Proof of the validity of these precepts came through the concept of trichromacy. reference Artists knew that combinations of red, yellow, and blue plus black and white would make all other colors. ❋ Unknown (2006)
In this determination to refine the practical details of trichromacy, Quemiset's work is again typical. ❋ Unknown (2006)
He used specific painting and engraving techniques to prepare three plates according to doctrines of trichromacy that were proved by Newton and supported more generally by mechanical philosophy. ❋ Unknown (2006)
Le Blon's woven-picture industry would call on the same principles as did his picture-printing — blending primary colors — and give to tapestry the notion of color-mixing that was prominent in the idea of trichromacy. ❋ Unknown (2006)
In the eighteenth century, without losing its original value to practical applications, philosophical experiments with red-yellow-blue trichromacy absorbed practices as its model. ❋ Unknown (2006)
The notion of primitive or primary colors that accompanied descriptions of trichromacy was derived from practice but it connected those practices to older traditions. ❋ Unknown (2006)
Like close to 6% of males, I suffer from anomalous trichromacy, also known as red-green colorblindness. ❋ Unknown (2010)
Analyses of the genes for those pigments give clues to how trichromacy evolved from the color vision of nonprimate mammals, which have only two kinds of photo pigments. ❋ Unknown (2009)
Although trichromacy is common among primates, it is not universal in the animal kingdom. ❋ Unknown (2009)
