Manganese violet is a fine, vibrant purple pigment that is synthetically generated. [12] It exhibits exceptional permanence and high lightfastness. [13] [14] The Waitress was created by Édouard Manet in 1879. Some artists historically avoided manganese violet because of they found its color to be dull.
These lamps emit ultraviolet light with two peaks in the UVC band at 253.7 nm and 185 nm due to the mercury within the lamp, as well as some visible light. From 85% to 90% of the UV produced by these lamps is at 253.7 nm, whereas only 5–10% is at 185 nm. [38] The fused quartz tube passes the 253.7 nm radiation but blocks the 185 nm wavelength.

Violet is the color of light at the short wavelength end of the visible spectrum. It is one of the seven colors that Isaac Newton labeled when dividing the spectrum of visible light in 1672. Violet light has a wavelength between approximately 380 and 435 nanometers. [2] The color's name is derived from the Viola genus of flowers. [3] [4]
It is known in medicine as Gentian violet (or crystal violet or pyoctanin(e) [1]) and is the active ingredient in a Gram stain, used to classify bacteria. It is used as a pH indicator, with a range between 0 and 1.6. The protonated form (found in acidic conditions) is yellow, turning blue-violet above pH levels of 1.6. [4]

Then Mozart adds two phrases of his own as a coda; in recitative, in free time and using only two notes: "Das arme Veilchen!" (Poor little violet!), a long general pause, and closing the song a tempo with a quotation from the third line: "es war ein herzigs Veilchen." (it was the sweetest violet.)
