Rainbow Color Palette with Every Hue Stock Vector Image & Art Alamy

A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. [1] The rainbow takes the form of a multicoloured circular arc. [2] Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.. Rainbow color names are the seven colors seen in a rainbow. These colors appear in this order: red, orange, yellow, green, blue, indigo, and violet. Rainbows are useful for learning color names, color order, simple science, art, crafts, classroom activities, and nature vocabulary. Kids often learn rainbow colors with pictures, charts, songs, worksheets, and the easy memory word ROYGBIV.

Colors like pink, gray and brown aren't in the rainbow because they result from combinations of wavelengths that don't appear as pure spectral colors. For example, pink is a mix of red and violet, which are on opposite ends of the spectrum.. What are the colors of the rainbow in order?
