Here are the rainbow coloring pages that are very simple and easy to color. This are suitable to be colored by children, especially early childhood and kindergartens.
Rainbow is an interesting natural phenomenon. When glowing, the colors are ready to make you fall in love. No wonder, rainbows inspire a lot, ranging from being made into songs, cakes, clothing, and much more. You may often see a rainbow, especially if the sun is strong enough and the rain is drizzle. Do you know how the rainbow process takes place? A rainbow occurs because of the refraction of light. Sunlight that passes through a raindrop will be refracted through it.
Well, this refraction process that separates white light into the color of the spectrum. Spectrum colors are red, orange, yellow, green, blue, indigo, violet. Then the colors bounce behind rain drops, which as a result looks light curving into a rainbow.
Actually, not only 7 colors of the rainbow, you know! Refraction on the rainbow will form all the colors that exist on this earth. But our vision is limited to distinguish them. So don’t be surprised too, if there are some people who can see a rainbow in 7, 6, or 5 colors. The same rainbow can be seen differently by different people because of the color perspective. One more thing you need to know, even though it looks like a rainbow is shaped like half a level, the shape of the rainbow is actually really a circle.
Well, you can also make homemade rainbows at home. Just provide a water spray that can remove drops of clear water as large as the size of rain drops. Find a location that is rather hot, then spray the water up. When the water drops, the water will refract sunlight into a spectrum of red, orange, yellow, green, blue, indigo, and purple.
