Want a fresh new look for your photos? Why not paint your car, without having to take it to the spraypainter? Want to try out a new colour on the house whitout spending the money on paint only to find you don't like it? Change colour on your hair,eyes or the clothes you are wearing, change the colour of almost anything. It's very important when you change the colour of something to change only the object and not change the colour of the surrounding items as well.
