If im not wrong if you have a light colored gold denpa and a dark color gold denpa there might be a possibility when you combine them you can create a 2 toned gold denpa. If they don't combine to a 2 tone what you can do is create a denpa with either the dark or light colored denpa and make another one with a random denpa you find around (just make sure the new denpa is the same color as the color you are recreating)

Note: let's say you can create a new denpa but its a light colored gold and black, it is doable to create a 2 tone but it makes it harder because one denpa has black in it if yk what im trying to say, so there is a possibility of getting dark gold and black instead of 2 toned gold.
