I honestly do not like orange with that floor . Check out Chilewich for a nice floor mat that is easy to clean and comes in great patterns and colors or just stick with a rug that almost matches the floor. I do like the orange as an accent like you have it though.Hang some cool art on the entry walls and just keep the mat really plain.

I wouldn't be crazy about orange because I feel like it would match the wood door, if that makes any sense at all. I would do a solid charcoal grey or black rug to tie in with the legs on your couch and coffee table. Your floor is busy so I think you need a solid rug.

I think a solid rug would look better with your flooring. Love the orange accent you have going on in living area.
