I painted these Artist Trading Cards with Tombow markers, using a variety of watercolor techniques. Sometimes I applied the marker onto the watercolor paper and then added water to move the color, and sometimes I scribbled the marker onto a paper palette so that I could pick up the color and apply it with a brush.
Mostly I don't see the point of substituting markers for actual watercolors, but I do like how bright and vivid the colors are. I don't have many Tombows, but chose the Jelly Bean set when I wanted to experiment with them because the set contains bright colors (like hot pink and lime green) that I don't have in my watercolor tube paints. So, I just may use them to mix and match with my watercolor paints and pencils.
