Next we'll change the stencil colors. Select the stencils you'd like to change. Remember to select multiple stencils,
hold down the shift key and click on each of the stencils you'd like to select. On the Style inspector, select the "Fill" icon.
This will give you all your fill options. Click the "fill color" box to open the color palette. This is the same palette you
used to change the background. Select a color. If a solid color is too boring for you, the "Fill style" area will allow you
to create different effects, such as linear blend, radial blend, double linear blend and double radial blend.
