Purple Wallpaper HD(圖1)-速報App

Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue. According to surveys in Europe and the U.S., purple is the color most often associated with royalty, magic, mystery, and piety. When combined with pink, it is associated with eroticism, femininity, and seduction.

Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the Emperor and aristocracy. The complementary color of purple is yellow.

In the traditional color wheel used by painters, violet and purple are both placed between red and blue. Purple occupies the space closer to red, between crimson and violet. Violet is closer to blue, and is usually less saturated than purple.

Monochromatic violet light cannot be produced by the red-green-blue (RGB) color system, the method used to create colors on a television screen or computer display. (In fact, the only monochromatic colors of light that can be produced by this color system are the red, green, and blue that define it.) However, the system is capable of approximating it due to the fact that the L-cone (red cone) in the eye is uniquely sensitive to two different discontinuous regions in the visible spectrum – its primary region being the long wavelength light of the yellow-red region of the spectrum, and a secondary smaller region overlapping with the S-cone (blue cone) in the shortest wavelength, violet part.This means that when violet light strikes the eye, the S-cone should be stimulated strongly, and the L-cone stimulated weakly along with it. By lighting the red primary of the display weakly along with the blue primary, a relatively similar pattern of sensitization can be achieved, creating an illusion, the sensation of extremely short wavelength light using what is in fact mixed light of two longer wavelengths. The resulting color has the same hue as pure violet; however, it has a lower saturation.

One psychophysical difference between purple and violet is their appearance with an increase in luminance (apparent brightness). Violet, as it brightens, looks more and more blue. The same effect does not happen with purple. This is the result of what is known as the Bezold–Brücke shift.

While the scientific definitions of violet and purple are clear, the cultural definitions are more varied. The color known in antiquity as Tyrian purple ranged from crimson to a deep bluish-purple, depending upon how it was made. In France, purple is defined as "a dark red, inclined toward violet".
