I thought i would show you howto change the color of the stitching
I used a bright red pen, when its got a shadow on it, it looks maroon, when the sun is shining it looks bright red.

Colors that would work great:

Red.
Yellow.
Black.
Light blue.
Bright green.
Orange.

You will need:
Red Sharpie.
Patience.

All you need to do is to use the sharpie as a brush rather than a pen and paint each individual stitch separately.
also i dot the pen in the needle hole between each stitch to make sure you dont miss any.
