Escape the terrorists

You think you can hide in the restroom and come up with a good idea to ask for help, so you go into the restroom and close the door.You see many bombs around you.You have been a soldier before and so you know something about the bombs. You think if you can dismantle the bombs, maybe you will be safe. You have never seen this type of bomb before. It has red, green, and blue wires all tangled around the bomb. If you cut the wrong one, the whole plane goes up in ashes. Which one do you cut off?
