Laser Cut Robot Stencil

Step 2: Prepare Layers: Part 1 Yellow

I selected the background of the image with the magic wand tool (fig 1).  Ctrl+command+i to select the inverse.  I selected the yellow color from the robot using the eyedropper tool.  I created a new layer and filled the selected area with yellow (figs 2 and 3).  Then I deleted the original image (background layer).  I used the erase tool to remove unwanted pieces from the remaining yellow layer.  I chose to remove the antenna and wheels from the yellow layer since there will not be any yellow on these parts in the final image (fig 4).
