download GIMP, a free equivalent of photoshop, and use it to open a photo of your house. then select these areas you want to simulate the colour change of and use the hue/saturation/lightness colour editor to tweak these regions until they are the colour you want. it is a bit tricky to learn but it's how i would do it. alternatively download sketchup (which is a 3d modelling program) create a plane, put the image on the plane as a texture, then use the line tool to cut the plane into pieces making a new face for each section you want to change. select each new face you've just made and then use edit-->face-->make unique texture. now go to your materials window and change the sliders for each unique texture to see them change colour.
Back on this site, for a while anyway, been so busy the last year.
