To mix or to match, that is the question ...

So last summer when the home expo jason's mom was working at was closing (in aurora), I swung by for the last few days of the sale and found some sconces I totally loved. They weren't a matching set, but they were from the same series. They were 70% off, and I had to buy them. So I did, and then set them aside for later. Lo and behold, in December there was a sale at homedepot online and I was able to pick up the mates to each sconce for roughly the same price I got them at expo! Here they are ...

As you can see, they are rust-colored with frosted glass and a satin nickel tip. We're putting the single ones in the bathroom, each flanking the tub, and the doubles are going into the bedroom, each flanking the entry area.

But here's the dilemma .... do we have to match our faucets to the fixtures? While a rust or oil-rubbed bronze would match nicely with these fixtures, I'm afraid they are probably going to be out of our budget, considering we have to purchase not only the sink, but a separate tub fixture as well as two different fixtures for the shower (one for the showerhead, and a different one for the shower sliding bar thingy (dontcha love my pro terminology? sorry, I lose nouns a lot). I'm thinking brushed nickel would be a lot more affordable, but is it taboo?
