Drawing with White Swim Lane Imports into PPT as Blue

[mcraghead]

I have created a very simple flow diagram that makes use of the swim lane shape. When I work on it in Visio 2013 the lane is white while its boarder and header are blue (default). However, when I import the Visio drawing into PowerPoint 2013 as an object (from existing file) the swim lane itself becomes a lighter shade of blue in PowerPoint.

I've tried playing around with backgrounds and anything that seems to make since, but I always end up with the same light blue swim lane. I'm not very skilled in Visio, so I'm not able to help myself very much. Any ideas on how to resolve this?
