Currently there is no way to change mframe colors or the image.

You can hack the resources, but the cache cleanup task kills these edits and with every plugin update they are killed also.

You can find them in your Emby \cache\coverart\4.1.17.0\resources.  Location shown on Dashboard Path box in 4.6 and in 4.7 will be relocated to three dot menu (view server info) on Dashboard or the top section of a server load after startup (does not appear in daily rollover log).
