Violet is at one end of the spectrum of visible light, between blue light, which has a longer wavelength, and ultraviolet light, which has a shorter wavelength and is not visible to humans. Violet wavelengths are between approximately 380 and 435 nanometers. Violet objects often appear dark, because human vision becomes less sensitive at ...
Common Blue Violet (Viola sororia) color variant. Viola sororia is a short-stemmed, herbaceous perennial plant that grows in well-drained and shady habitats. [ 5 ] This 15–25 centimeters (6–10 in) wide violet has glossy, heart-shaped leaves and are topped with purple flowers with white throats. The lower three petals are hairy and the stem ...
RGB color model. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

White light is dispersed by a prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light). The optical spectrum is sometimes considered to be the same as the ...
White light-emitting diodes (LEDs) became available in the mid-1990s as LED lamps, in which blue light emitted from the semiconductor strikes phosphors deposited on the tiny chip. The combination of the blue light that continues through the phosphor and the green to red fluorescence from the phosphors produces a net emission of white light. [79]
Periwinkle is a color in the blue and violet family. Its name is derived from the lesser periwinkle or myrtle herb (Vinca minor) which bears flowers of the same color. The color periwinkle is also called lavender blue and light blue violet. [2] The color periwinkle may be considered a pale tint of purple-blue in the Munsell color system, or a ...
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System. In the photograph, Earth's apparent size is less than a pixel; the planet ...
