Step 5 - Setting up new layers

In this step, we'll set up a layer structure for applying color.

First, select the Background layer. Next, go to the color swapper in your Tools window. If the swatches (those squares) aren't black and white already, click on the miniature B&W swatches below them. This will revert the swapper to B&W. Next, click the little swapping arrows above the swatches to swap colors, making white the top color.

Go to Edit>Fill. The contents should be your foreground color (white, which you just picked), the mode Normal and the opacity 100%. Click OK. You just turned your background white.

Go to Layer>Flatten Image. In your layers window, you should see Layer 1 and the Background layer merge into one now just called Background.

Duplicate the background layer by going to Layer>Duplicate layer. Finally, rename the top layer "Line" and the bottom layer "Color."
