All depends on the year the Royal was made I suppose. And the type of room too. Is it an office, a home study, a library, or a den? If you want the machine to be in an authentic period theme then you really need to start off with a manufacture year. On the other hand, contrast is often interesting too. A vintage typewriter in a stark, ultra-modern setting can really create more emphasis on the typewriter.

I think you need a gooseneck desk lamp, with a semicircular reflector around the bulb to direct all the light downward.  Also, a heavy glass ashtray (mostly full!).

My dad has one of these with the fold up typewriter compartment in his basement.  But, they painted it with some weird antiquing paint in the '50s (kind of an off-white with blue and pink speckles in it).  I have said that I would like it at some point.  They did this to all their furniture, including an old cabinet radio (they no longer have it) and an old Victrola (still there with the paint on the outside.
