So, I am putting this print (NOT CANVAS LIKE IN PICTURE, BEHIND GLASS GICLEE PRINT) on this gray wall. Frames in other parts of foyer are silver and I have a white mirror and white entry way table. Three specific questions below:

1.) What would be a good color frame?
2.) What would be a good color primary mat (2-3 inches)
3.) What would be a good color secondary mat (1/4 inch accent)

Some have already said a black frame but I've been hesitant to do that because of the frames in the room already. I had wanted to do silver with a hint of gold in it.
