Cheapest way get some spray paint. They have metal looking finishes in all sorts of colors. Just clean and lightly sand/use steel wool before spraying. Quite a few years ago I was re-finishing a desk and was going to re-place the drawer pulls but couldn't find any new ones that matched the holes (they were brass plated and in bad shape)I found a place that re-finished them using electroplating. They were able to put the brass back on and finished with a clear coat. 20 years ago it was about $60 for 7 handles. I may be quite expensive to do that to a bakers rack.

What makes you think it's plated?
Try removing the laquer with laquer thinner and paper towels and then use a brass cleaner....I'll bet it polishes up.

One way to see if brass plated is to use a magnet. Won't stick to solid brass. My mother in-law showed me this trick while antiqe shopping.
