Excuse me, should the door cover of the security door be the same color as the security door or the inner door?

According to the experience of Opel Longmen Company, most entrance door covers are the same color as indoor doors. The first reason is that it is convenient to place a one-time order when decorating. The second reason is that the surface of the security door is mostly iron, and the entrance door cover is mostly wood. It takes a lot of time to install the wooden porch cover with the same color as the iron security door.
