Pocket fold invites - what colours look best?

Hi, I'm totally lost atm with what colours to use with my diy pocket fold invitations. The pocket folds are ivory and the paper is ivory I want to use a glitter card mat to stick the invite on but not sure if to use silver or blue. Our wedding colour is turquoise blue. Just not sure what will look better or if I should use a different colour paper then ivory. Thank you
