When people think of coloring, there’s a few typical coloring accessories that come to mind. Adult coloring enthusiasts tend to look for colored pencils as their coloring tool of choice. And why not? They lay on dry, are relatively cheap, come in a wide variety of colors, etc. Markers and crayons seem to be great choices for children (but we’ve met a lot of adult colorists who love both markers and crayons). Gel pen art is an art medium all its own so there’s no reason not to color your coloring books with gel pens. If you haven’t tried gel pens with your coloring books, then you are missing out on a very versatile and interesting coloring tool that will set your coloring apart.
