3. Now do: Filter > Pixelate > Crystalize..., and set it to 3. Then click the box next to the Quick Mask Mode to return to normal mode. Save the selection by doing: Select > Save Selection... Now fill the selection by: Edit > Fill, and fill it with whatever color you want. Then do: Select > Modify > Expand... Enter a number that suits your taste. Click Quick Mask Mode and do: Filter > Blur > Gaussian Blur... with setting of 3. Go back to standard mode.
4. Do: Select > Load Selection... select your saved selection and check Subtract from Selection and press OK. Do: Image > Adjust > Hue/Saturation... and click the Colorize check box. Set it as follows: Hue: 14, Saturation: 31 and Lightness: -80 or so. Bing bang boom, you got burned edges with out the fire.
