Did you know? It is believed that the colors of a rainbow are determined by the specific wavelengths of light that are refracted through water droplets in the atmosphere, with red being the longest wavelength and violet the shortest.

Creative Coloring Ideas:
• This black and white printable rainbow has multiple ways to be colored. Here are five ideas:
• 1. The sky is blank, so it can be any color you like.
• 2. The grassy area at the bottom of the picture could be green or a different earth tone.
• 3. The rainbows itself could be red, orange, yellow, green, blue, indigo, violet, or whatever colors you wish to choose.
• 4. The three plants in the middle of the image can have any color leaves as long as they are not too similar to the sky or rainbow.
