Decided to add some color to Ivy. And I did it differently than I normally do. For this piece I layered the colors and didn't blend them. No gradients and no airbrush effects. For example, there are three different values for her tights: Dark, medium and light green is used. Same with the skin tones. And then some white for the "hot" spots. But used sparingly.
The background is where I played with a watercolor brush set with a low opacity. This allowed a transparency to the colors. Colors bleed into each other and could be seen through each other. The idea was to have a softer background to add contrast to the hard edges your eyes have to blend on Ivy's coloring. All the colors were done in Photoshop CS3.
