Here is a really lovely, intricate but also pleasingly simple rangoli design to colour in! It would be interesting to see how differently a group of children would interpret the pattern, all using the same colours...
Rangoli Colouring Page 9
This is a traditional grid-based rangoli design, where dots are first marked and then loopy lines drawn around them to create a clever pattern. You see these drawn in white chalk powder, and then possibly embellished with other colours.
This pretty circular design is fun to colour in. Use bright rangoli colours or do something completely different!
