TDI, I know EXACTLY what's happening. Same thing happened to me. You need to make a new layer (in that layer box in the corner) and then drag the layer under your line layer. Go up to the line layer and use the magic wand to select what you want colored, then go back to the color layer. Finally, click the bucket and color it in. You're welcome. :3
