Prism doesn't add colors to white light, it just dissipate the all colors of white light into different direction. White light contains all seven colors in it. So don't be confused in the addition of colors into white light or dissipation of all colors, containing in white light.
A dispersive prism can break light into its spectral colours, or the colours of the rainbow
A prism will split white light into its constituent colours (the colours of the rainbow). "White light" is the light we see around us i.e. natural light from the sun. This light is made up of all the colours in the visible spectrum
This is because when the white light it's the prism, the colours separate and change speeds.
When white light passes through a triangular prism, it refracts, meaning, the light bends. When white light refracts, it disperses (separates) into the colours it is made up of - ie. the colours of the rainbow.
When white light passes through a prism it separates into its component wavelengths that we observe as colours.

It is the refraction of white light being shone through a glass prism, or a raindrop, that separates the white light into the colours of the rainbow.

White light separates into seven colours
Light appears white, however it is made up of different colours, which when put together make white light. These colours can be seen if you direct light through a prism. At the right angle the light is split up into the colours (rainbow).
You may use a glass prism and shine a white light through it. You will notice that there is rainbow of colours on the wall.
Because white light, when shone through a prism, will divide into all the colours. And all the colours, mixed together, will combine into white light.
