That might just be what the supplier calls it because gold sounds more appealing than beige-brown in today's market.
This whole gold trend is getting out of hand, especially with anodizing.
The architect is probably looking for Gold Anodizing which costs an arm and a leg and there are very few vendors in Ontario that offer it.
The issue with it is that all your material has to be anodized at the same time to get the same finish and there is no guarantee that the batch will be consistent throughout. At some point, the vendor has to clean the tanks, and you'll get a variation on the finish, which ends up looking awful. Especially if welding is involved.
You can also get a post-painted gold mica finish, which is more consistent than anodizing. but for some reason architects balk at painted finishes.
I'm getting nightmares because my company did the interior panels at the Drake Hotel and the architect insisted on anodized finishes. We kept telling them (and made several samples) that for what they wanted to do, a painted finish would be so much better (not to mention the cost savings). Nope. Anodized. We threw away so many panels because of the inconsistencies.
