This tut will show u how to make a quick and easy background for your sig, using photoshop.
step 1: make a new page and place your render on it, make sure it touches the top and bottom edges of your page
step 2: choose the rectangular marquee tool and select a thin section of your render like this:
step 3: press ctrl+J and then hide the render layer
step 4: press ctrl+T and stretch the selection to fill the entire page and press enter. we will call this the background
step 5: unhide your render layer and move it ontop of the background layer. then make new layer
ontop of everything and fill it ,using the fill tool, with a colour suited to your render, i chose a deep red. set it to overlay in the layers palette and reduce opacity accroding to what looks good.
You're done!
