Kwanzaa is celebrated in the US from December 26 to January 1. See the associated wikipedia page for more info. USPS has issued several stamps over the years. The current one, issued in 2016, caught Heleen's eye, and she had asked me (a long time ago) to send her some on mail. I hadn't forgotten, and I thought this page of fruit from a coloring calendar would work with the stamps.
I used inktense pencils to color the page, then afterwards went over it with a wet paintbrush to bring out the colors.
