Brown, plum and lavender:

Royal purple, burnt orange and brown:

Black, purple and orange:

And here is a perfect match for my Halloween theme! I am leaning really heavily towards this once I saw how great the purple and orange can go together. I was worried about it being tacky but it can be really elegant. Thoughts?
