Does anybody knows a method/graphic program to delete these background colours?

I don't think there is one. Usually for something like that, you turn off the background layer in the emulator to make it easier to get the sprites. Some emulators don't support that though so if that's the case you'll have to get rid of the background by hand. That or you could maybe extract the sprites straight from the ROM with a tile viewing program or something.
