Violet and purple almost look the same, people often confuse them as the same colour. Scientifically violet and purple are two different colours.
Violet colour is an original color or spectral colour that is present in the visible light spectrum. Violet colour has its own wavelength 380 nm to 450 nm in the visible spectrum.
Purple colour is a man-made colour, it is a non-spectral colour that is formed when red colour and blue colour are combined.
In this brief article, we will explore what is violet colour, what is purple colour and what's the difference between violet and purple colour.
Violet colour is the spectral colour found in the visible light spectrum. It has its own wavelength in the visible light spectrum, 380 nm to 450 nm. Which means it is one of the colour which is visible when white light passes through a glass prism. In all the spectral colours Violet has the shortest wavelength.
Purple colour is not found in the visible light spectrum, so, it is commonly known as non-spectral colour. Purple colour usually formed when red and blue colors are mixed. In addition, our brain thinks its seeing purple colour when red and blue or violet colour reaches together at the same time.

What is Violet Colour
Violet colour is the spectral colour found in the visible light spectrum. It has its own wavelength in the visible light spectrum, 380 nm to 450 nm. Which means it is one of the colour which is visible when white light passes through a glass prism. In all the spectral colours Violet has the shortest wavelength.
What is Purple Colour
Purple colour is not found in the visible light spectrum, so, it is commonly known as non-spectral colour. Purple colour usually formed when red and blue colors are mixed. In addition, our brain thinks its seeing purple colour when red and blue or violet colour reaches together at the same time.
Difference between Violet and Purple Colour
| Violet | Purple |
| Type | |
| Violet is a spectral colour found in the visible light spectrum. | Purple is a non-spectral colour and is not found in the visible spectrum. |
| Wavelength | |
| Violet has a wavelength of about 380 - 450 nm. | Purple does not have one specific wavelength. |
| Formation | |
| Violet comes from a specific range of wavelengths of visible light. | Purple is usually formed when red and blue or violet light reach the eyes together. |
| Prism | |
| Violet can be seen when white light passes through a glass prism. | Purple does not appear as a separate colour when white light is separated by a prism. |
| Applications | |
| Violet is used in lighting, optical studies, and scientific applications. | Purple is commonly used in paints, clothing, printing, art, and design. |
