Roman Shades with Trim

With this new house I have developed quite an affinity for roman shades.  We have white roman shades in our bedroom and also added a pattern twist on a roman shade to the nursery.  The only windows that are left bare in the house are in the game room/play room upstairs that I recently updated with pillows (see here).

I didn't know what I wanted to do with the windows when we moved in because they provide the only view in the home and we don't need to cover them for privacy reasons so we did nothing.  Yet it now looks unfinished, so I would like to add something there sometime soon.  While I like how soothing the plain white roman shades are in our bedroom I would like to do something a little more fun in there without being committed to a pattern.  I have always loved the look of colored trim on a stark white shade like these inspiration photos:
