I began this abstract drawing with a dark brown calligaphy pen, moving into lighter browns and tans, and finally using orange, pale peach and yellow. I knew all those colors worked OK together, but the drawing needed more oomph. I added some aqua and then blue lines. After that I filled in some of the blue and green shapes with a pale blue brush pen. This seemed like too much blue, so I went over some of the sections with yellow, turning the blues into greens. Finally, I outlined some of the inner shapes with a fine point black pen.
