It's called a spectrum.
Roy G Biv
Because the sunlight which is white gets disperced (split) into the colours of the rainbow hence the name rainbow.
The acronym for the colors of the rainbow is ROYGBIV, which stands for Red, Orange, Yellow, Green, Blue, Indigo, and Violet. This sequence represents the visible spectrum of light as it appears in a natural rainbow. Each color blends into the next, creating the beautiful array seen in the sky.
Red, orange, yellow, green, blue, indigo and violet.
There are seven colours in a rainbow. In order, the colours are Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
