index doodles - circular rainbow, cool

Index doodles! Hello! I don't know why I didn't do them for a while, but a few weeks I decided to start them again. These are super simple and good to do while listening and easy to start and stop - just circles in the forms of dots, small circles and large circles in a limited palette, but I really like the resulting patterns. Hopefully I can work on the warmer colors for a complete rainbow next!
