That sounds like a great plan. You can do some cool stuff with double mats and intricate frames but it is really hard to do that and keep a gallery presentation theme intact.
In custom picture framing the frame package becomes an extension of the art and in ideal cases it becomes an extension of the place where the picture frame will be displayed. The photo becomes a part of a larger art piece...the room. Some times custom framers have to do things they feel hurt the image and use a mat or frame color that is wrong for the image but matches a sofa in the clients house. In gallery style framing the idea is the opposite. A simple white mat, black frame to set the image off the wall and highlight it without detracting from the image.
In your case your primary mat will be the same as the rest of the pieces in your display maintaining your theme but you will have small bottom mat that sets the image off from the Pearl White mat so that it is not distracting from the image.
