In common English usage, purple is a range of hues of color occurring between red and blue. [1] However, the meaning of the term purple is not well defined. There is confusion about the meaning of the terms purple and violet even among native speakers of English. [2]
Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both.
Violet refers to any colour perceptually evoked by light with a predominant wavelength of roughly 380–450 nm. Tones of violet tending towards the blue are called indigo. Purple colors are colors that are various blends of violet or blue light with red light.
Violet is closely associated with purple. 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.
Colors that can be produced by visible light of a narrow band of wavelengths (monochromatic light) are called pure spectral colors. The various color ranges indicated in the illustration are an approximation: The spectrum is continuous, with no clear boundaries between one color and the next. History
The theory of color includes the color complements; color balance; and classification of primary colors (traditionally red, yellow, blue), secondary colors (traditionally orange, green, purple) and tertiary colors.
Light becomes decomposed through refraction, inflection, and reflection. Refraction, inflection, and reflection can exist without the appearance of colour. Analysis White light decomposes into a spectrum of all colors. There are only two pure colours—blue and yellow; the rest are degrees of these.
Purple. Purple is truly one of the most remarkable colors! It cannot exist without the mixing of red and blue pigments, which is why it's associated with creativity and magic.
The color scheme of François d'Aguilon, where the two simple colors of white (albus) and black (niger) are mixed to the "noble" colors of yellow (flavus), red (rubeus), and blue (caeruleus). Orange (aureus), purple (purpureus), and green (viridis) are each combinations of two noble colors. Light and color vision
True color is measured after a sample of water has been collected and purified (either by centrifuging or filtration). Pure water tends to look cyan in color and a sample can be compared to pure water with a predetermined color standard or comparing the results of a spectrophotometer.
