We have long discussed the need to replace the standard hinges that were installed with our wooden doors. After much research we decided on Emtek brass (in flat black to match the interior knobs) heavy duty ball bearing hinges.
Similarly, the creamy plastic switch plates and the white metal walled register vents needed some attention (the floored registered vents already blended nicely). We considered, and were fairly certain, we wanted to dress these up in scrolly wrought iron, however, we decided to instead blend them into the background rather than make them pop. We have a small space and agree less is more.
Note that we *did* order the switch plates in iron and something to consider, which we had not previously, is the color of the switch itself-that you flip or push on and off. Meaning, ours are cream colored and contrasted horribly with the black metal. The cream color can easily and inexpensively be changed to grey or black (or whatever color you like) to better match the plate but nonetheless this was still just a bad look in our opinion and is what drove us to blend instead of pop. (Same issue with the color of the plug portion of outlets.)
Once in the "blend" mode we continued with the register vents.
