Even more so, there can be up to 3 rainbows from a single light beam, because the light beam undergoes one reflection and two refraction inside the water drop.
One that you can clearly see.
A second one that is barely visible, but still can see it if you pay attention and if nothing blocks your line of sight. Also depends on the the sun's position. It has inverted color order.
And then a 3rd one, which no matter how you try and position yourself will always be located "behind" you, thus never visible.
PS : Looks like tertiary rainbows CAN happens under exceptional conditions.
