There are a few heat

There are a few heat discolorations you can do to stainless- Guiseppe is the expert on that.
Heath actually uses a solution to rust the stainless to get his color.

Steel is a bad idea, as is aluminum.

Real Copper or bronze is probably the best thing- the patinas that have been devised for it, over the last couple of millenium, are available in the widest variety of colors and last pretty well.

Of course, its fiendishly expensive.

Architects, although they are loathe to admit it, are herd animals, extremely sensitive to fads and trends.
Several of the best known, most prestigious firms have been doing these types of patinated metal panels lately, and all the other architects want to jump on board.
The problem is that when Herzon and De Meuron does it on the De Young Museum in San Francisco,

they have a budget of $202 Million dollars.
This allowed them to hire these guys to make their computer punched and textured, patinaed copper sheet facade.

Zahner is the best there is- millions of dollars worth of CNC equipment, a very experienced work force, and their client list is the absolute who's who of world class famous architects.

There is no cheap, home shop way to do this- the raw materials are VERY expensive, the patina techniques are slow and labor intensive and require experimentation, the sheet metal tools to make this stuff look good cost tens of thousands of dollars.

If your architect has a LOT of money, then there are a variety of copper alloys that will work well. They can be patinaed in a range of colors.
