Never saw a rainbow, two measures? Or a rainbow around the moon than the sun? Or a triple rainbow?
Once I saw a double rainbow then, look, lightning came from the center of the arc to their inner edges. I was perfectly sober, too, if requested. I also saw a lunar rainbow, "" repeatedly. Once could even distinguish colors, although only slightly. Never saw a triple rainbow, although I know they are produced.
Celebrity Heaven are quite common. As with the regular rainbow, the sun must be behind you and should not be the rain in front of you. To form the double rainbow in the rain only requires be more widespread and that the sun is shining. Look for striped green and pink on the inside arc. "Arcos Luna" are also quite common. For them, the conditions you should be very cloudy or ice crystals in the upper atmosphere. You can also search for other conditions as "sunDogs' where there is a partial rainbow each side of the sun (from ice crystals) and the "pillars of the sun", where a tower of light appears on the sun.
