Viola sororia ( / vaɪˈoʊlə səˈrɔːriə / vy-OH-lə sə-ROR-ee-ə ), [ 5] known commonly as the common blue violet, is a short-stemmed herbaceous perennial plant native to eastern North America. It is known by a number of common names, including common meadow violet, purple violet, woolly blue violet, hooded violet, and wood violet.
Eye color. Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye 's iris [ 1][ 2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [ 3]: 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of ...

Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in dim light ...
Tritans see short-wavelength colors (blue, indigo and spectral violet) as greenish and drastically dimmed, some of these colors even as black. Yellow and orange are indistinguishable from white and pink respectively, and purple colors are perceived as various shades of red. Unlike protans and deutans, the mutation for this color blindness is ...
Impossible color. The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types. Impossible colors are colors that do not ...
In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, [5] [6] some of which humans perceive as similar to violet. In common usage, both terms are used to refer to a variety of colors between blue and red in hue.
Starting at the root chakra, these colors go from red to orange, to yellow, to green, to blue, to indigo, to violet. “If we are sad or depressed, there will be darker colors on our aura readings ...
