Is this silver?

[AllSeasons]

I recently purchased these items below. As you can see, there is a piece with 3 connected figurines. On each of those figurines, there is a ribbon that's of a different color. I'm having a hard time figuring out whether those brown ribbons are also made of silver. On the back of the piece, it says sterling (small). I've never seen brown silver before. Do you think the ribbons are silver, or perhaps copper or brass? Thank you in advance!

Hi,

A close-up image of the marks would be appreciated.

Sorry for the delay - I just received the item on Sunday. I was able to take a higher-res picture, though it's still not coming out too clear. In any case, here it is. I'm pretty sure the 3 figurines are sterling, but the ribbons look like copper?
