Sepia or B&W with a purple and green theme?

Posted under black futon

I am redoing my room. Age 15 female. I am wanting to do a rich purple wall color (Dutchboy Regal Dream) with green, like a muted lime, accents. I plan to have 6 silver frames above my futon. 3 will be pictures of my pets and 3 will be mirrors. In a checkerboard design. 2 high 3 wide. I want to know if I should use sepia or black and white pictures.

I think the black and white would go better with the sophisticated theme. Plus my furniture will be black.

Black and white will look clean and cool against the purple. Sepia will be too muted. I think in the silver frames, the black and white will look good but the sepia would contrast a bit.
Good luck with your project.
