Minimal Rainbow

We all saw this beautiful sight, these magical colors in the sky. Imagine that there was a huge rainstorm, it ended, and the sun is starting to come out from the clouds. The sun's light gets bent and reflected inside of water droplets and you can see sunlight in the new magical colors - colors of the rainbow. Rainbow's pattern of colors starts with red on the outside and changes through orange, yellow, green, blue, indigo, and violet on the inside. Minimal cursor with a Rainbow!
