There are 7 rainbow colors. Red, orange, yellow, green, blue, indigo and violet. Because of all these colors it is really fun to color a coloring page of a rainbow. People tend to get happy when they see a rainbow high in the sky. It is a beautiful sight and doesn't happen everyday. We are sure that our printable rainbow coloring pages will also give you a smile on your face. Will you pick a simple rainbow, or a rainbow with a unicorn? Also when you are an adult you will find rainbow pictures of your liking. You can see a rainbow in the sky when sunlight passes through the raindrops. About that pot of gold.... You have to search for the end of a rainbow for a very, very long time. A rainbow has no beginning and no end. What you see is a half circle, but actually it is a full one. You can only see the full rainbow when you are very, very high above the earth (in a plane for instance). A rainbow also represents diversity. A rainbow always shows its colors in the same order, with red on the outside and violet on the inside, and you can only see one when the sun is behind you. Color the bands in that order: red, orange, yellow, green, blue, indigo and violet, and add a few fluffy white clouds at the ends.
