ORB is a living finish, and the more you use it, or clean it, the more the bronze underneath will show. It's your choice as to whether to live with that or not. But, no one on the planet is going to come to your house and stare at your sink strainers and give you a look of pity because you didn't "upgrade" from clean, hygenic, non staining, stainless or chrome.

Oh my! I can't help but laugh. I definitely am not worrying about someone else looking at it. I live in the middle of a cow pasture. It doesn't look like its changing colors, it looks like a finish is coming off. I paid $50.00 each for them and now not sure I can get by with changing out just one.
