What colour is a moonbow?

Directions: Read the following passage and answer the question that follows:

Rainbows! Rainbows! The sight which the children love to see. They are awestruck when they see the magnificence of the colourful arc. These wonderful arc like structures are caused when sunlight shines through drops of water in the sky at a specific angle. It is the rainstorm which becomes the birthplace of the rainbows. Rainbows are often seen when the sun comes out after or during a rainstorm. When white sunlight enters a raindrop, it exits the raindrop in a different colour. The rainbow is also called ‘VIBGYOR’ when it exits lots of different raindrops at different angles. The different coloured lights are: V is violet, I is indigo, B is blue, G is green, Y is yellow, O is orange and R is red. Together, these colours are known as the spectrum. These colours can sometimes be seen in waterfalls and fountains as well. We can see double rainbows, meaning a rainbow which forms two arcs. In other words, the order of colours starts with violet on top and ends with red on bottom. Believe it or not, rainbows sometimes appear as white arcs at night. These rainbows are called moonbows. Moonbows are caused by moonlight (rather than sunlight) shining through drops of water.
