Rainbows have seven colours which are red, orange, yellow, green, blue, indigo and violet. The five main colours are red, yellow, green, blue and violet. Orange and indigo are made to connect the colours.
You can see rainbows that are circular when skydiving depending on the weather. Reflection rainbows and normal rainbows are seen on rainy days at sunset.
Rainbows are formed by millions of rain drops and the sun shining through them to bring out the beautiful colours. They also may be formed by the spray of waves, then they are called spray bows.
I have told you how rainbows are formed. I choose to do rainbows because I wanted to find out how they were formed and I leanrt that the sun has more than one colour, but yellow is one of the main colours.
