1) Get a good picture like
mine here

2) Now use the pen tool, the lasso tool or the magic wand tool to select the red part like in the picture.
3) Create a new layer and fill the selection with a color of your choice
4) Set the blending mode of that layer to "color" All you have to do now is to add some details.
5) heres a few examples Imade.. Recolored using hue/saturation.

6) Just a selection with the polygonal lasso and deleted the selected part
7) added details using the pen tool.
