Rainbow effect is formed by reflection, refraction and dispersion of light in water droplets.
It is impossible to observe a rainbow at any angle other than 42 degrees from the direction opposite the light source.

In a primary rainbow, the outer part of the rainbow is red and the inner part is violet.
A secondary rainbow appears outside of a primary rainbow. The color scheme of the secondary rainbow is opposite of the primary rainbow.
