Primary rainbow
This is the most commonly seen in the sky.  It forms 40 to 42 degrees of anti solar point (an imaginary point opposite to the sun).  If there are smaller reflective droplets, only violet color will be visible.

Supernumerary rainbow
This is a special rainbow.  It needs interference of light rays of different wavelengths to be formed.  It appears on the inside of a primary rainbow and it is faint in color.  The faint pastel streaks of color also form outside the secondary rainbow though it is rare.

Lunar rainbow
This rainbow is not form by sunlight but moonlight.  It appears on the Lunar month when the moon is nearly full, form by the light from the surface of the moon, reflecting in tiny droplets that cause the refraction and stream of color eventually.  It usually appears in a white faint bow on the outer rim of the moon.

Fogbow
This particular rainbow is not formed by rain but fog.  This happens when water droplets are too tiny for light to pass through in the same manner as in a normal rainbow.  And when inadequate color dispersion of light takes place, it results in a white band known as white rainbow.
