If you want your couch or item to be black, you might not want to automatically dye the couch the black color. Instead, you should start with a lighter color and then work your way up to the black. Say you have a white couch and you want it to be black. You would first want to dye it a color darker than white, such as green. Then something darker than green, like dark blue. It is only then that you would dye the leather black. If you use black leather dye without darkening the fabric, you might not get as dark of a result as you want. By dying it shades at a time, you will end up with a deep, dark color that is sure to be exactly what you are looking for.
