Did you know? The primary cause of rainbows is the refraction and reflection of sunlight by water droplets in the air, resulting in the formation of an arc of colors that appear in the sky after a rain shower or near a waterfall or mist.

Creative Coloring Ideas:
• Sure, here are five ideas to color your rainbow picture:
• 1. Rainbow Over Water: Fill the sky and clouds above the rainbow with bright blue colors, add some fluffy white or light gray clouds around the rainbow, and paint the water below in a calm shade of blue or green.
• 2. Rainbow Under The Sea: Create a whimsical underwater scene by painting the sky and clouds above the rainbow with shades of blue and purple, filling the sea below with various types of fish, and adding some seaweed or coral to complete the picture.
• 3. Rainbow at Sunset: Bring your rainbow to life by painting the sky behind it in warm sunset colors like orange, pink, and yellow, adding a few fluffy clouds around the rainbow, and painting the ground below in earthy tones such as brown or beige.
• 4. Rainbow With Unicorns: Add some magic to your picture by painting unicorns standing on either side of the rainbow, creating a beautiful and imaginative scene that will delight kids and adults alike.
