As the name of a color, violet (named after the flower violet) is synonymous with a bluish purple. Since Isaac Newton listed violet as his name for the color of the short-wavelength end of the visible spectrum (approximately 380–450 nm), when both of the names purple and violet are used within the same system, violet tends to represent colors nearer to blue, while purple is used for colors more nearly between blue and red. Objects reflecting only light wavelengths in the aforementioned “violet range” would appear very dark, because human vision is relatively insensitive to those wavelengths, but the color of a monochromatic light source emitting only those wavelengths can be roughly approximated by the color shown below as electric violet.
