The brown and orange autumn colours in this kaleidoscope colouring page feel like a good match for the time of year, since the weather here has just started to get a bit chilly, and the leaves are beginning to turn. I coloured it using Tombow brush markers.
This illustration is from my Through the Kaleidoscope Colouring Book, which has 50 abstract full page mandala designs. You can see all of them here, or buy the book from Amazon.
