I like this living room  

Stout steel rods.
The big box home improvement stores have copper-clad steel electrical grounding rods for cheap and you wouldn't need to paint them, as they turn a dark brown quickly and, eventually, a nice verdigris. You'd need to improvise some sort of flanged clamp, though, to keep the pots vertical. Maybe three little galvanized "L" brackets held to the rod with a band (hose) clamp?

That sounds good.
An easy single-rod method would be to use all-thread (threaded steel or brass rod) available at almost any hardware store. A length of that, fastened to the pot through its central hole with two nuts and two fender or standard flat washers, would be a quick solution. I don't know enough about plants to know whether additional drain holes would be needed. Perhaps the multi-prong lock washers would provide some trickle drainage ?

SDR, you're suggestion is better.
Drilling ceramics is the tricky part!
Oh, and I think it's the warm light on the bronze skin tones. Imagine a lover with the surfaces of that sofa.

I've had 100% success...
I've had 100% success drilling holes in heavy vitreous clay pots using a masonry bit in about 1/2" of water.
Steel rods will eventually rust away and crumble but it might take a long time, especially if you use plants with low water needs. I like the copper-clad rod idea a lot, though.

Worked on it today
I drilled the pot with a 1/4in masonry bit, then used 3/8in metal tubing and 1/4in threaded rod that I got from a local metal supply place for the post. I put it all together with some washers and nuts and mounted on a 4x12 piece of lumber that I put a countersink in on the other side.

Good work!
It looks almost as if it's levitating, which is a bit strange, but perhaps when the install is complete it won't seem so.
I guess the relationship between the television and framed print in the photo of the room attached to the OP isn't working for me. The big black rectangle needs to go.

Note to self:
Do not ever post pictures of your living room. The preponderance of greys, boring oak floors and 55" idiot box will get you comprehensively lambasted. Although this does lead me to another question about living room decor for which I will start a new thread.
