Violet
One device that splits white light into the colors of the visible spectrum is called a prism. It is a triangular piece of glass through which a narrow band of white light can pass. The blue color light is bent most, and the red color light bent the least. So the colors in-between red and blue are seen on a screen as a spectrum. A rainbow is produced when drops of water in the sky have light passing into them, and the light is bent in a similar way, producing the spectrum. So there are many devices that can produce a spectrum of the colors.
Blue
Blue bends best. The blue/violet end of the spectrum is bent the most, i.e. has the highest refractive index. Thus the lowest index is for red.
Blue bends best. More precisely, the shorter the wavelength of the light, the more it is refracted. The blue/violet end of the spectrum is bent more than the red end.
Red bends the least. If you look at a prism with a beam of light shining through it, you will see violet is bent the most. This due to the refractive index of the glass changing the wavelength. Velocity & frequency are components of wavelength. So the refractive index is a ratio by which the speed of light is changed. I am not sure if frequency is changed.

White is the combination of ALL of the colors of the visible spectrum or rainbow.
Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
