I can't decide what color to paint my bedroom. I want to see how my bedroom would look painted in various colors/shades. I took a picture of my bedroom. The walls are now a light color. When I use the fill bucket it fills in the walls with my new color but it also fills in my bed ruffle and base boards as they are a light color also. How can I use Gimp to see what my bedroom would look like painted in various colors/shades without painting the bed ruffle and base boards? I LOVE this site! Thank you for any help you can give me or point me to.
