Good Luck Fran1988!
The day I was braced I stuck with silver ( boring, yes I know, but with the shock of braces that was all I was wiling to take) It worked out very well for me as I was feeling unsure about the braces. I have metal braces btw.
The second adjustment I went with light blue ( not very noticeable, but cute) the only problem I had was they made my teeth seem more yellow.

I haven't gone with them since.
Now I alternate, sometimes I am "boring" as my son tells me and I go silver, and sometimes I go with light pink. They look very cute as well and not too bold. I am more conservative I guess, but I am not self conscious of my braces anymore so I would go with whatever I liked.
If your comfortable with colors,
go for it! I found that no-one seems to notice colors that much anyway ( other than yourself) If you think you'll feel uncomfortable the first time around until you get used to them, go silver ( or smoke if your going with ceramics as they don't stain but are unnoticeable)
Good Luck!! Make sure to take pics to share!
