One potential gift idea for your friend who likes coloring could be a set of high-quality coloring supplies - such as markers, colored pencils, or gel pens - along with a coloring book or two featuring designs that you think they would enjoy. Alternatively, if your friend already has a lot of coloring supplies, you could consider getting them a subscription to a premium coloring book service that delivers new books to their door each month. Another option is to buy them a personalized coloring book or coloring page featuring their favorite things or a funny inside joke, which can make it feel more meaningful and personal than a generic coloring book.
