A couple of months ago I bought a 65” Harmony to replace our BV11-55. 

We chose a custom walnut/aluminum (standard is walnut/bronze now… go figure) cover for the Soundcenter in order to match the existing 4 BL18 which we got in 2015.
We returned the cover because the color tone of the harmony was totally different from the speakers and B&O is not able to match it.
So we chose to stay with standard grey/black cover which is the bless worse option.

Question is can I spray paint the cover to make it completely back? Any suggestions about which product to use?
