tuxedo help!!

My dress is ivory, so everyone says we have to go with ivory shirts, which kills my plan for dark silver vest/tie for the bp and light silver for fh...the light silver looks terrible with the ivory, the dark is ok. So, we decided on black for the bp and ivory for fh, but now we are rethinking that. Does the ivory on ivory get lost in pictures? Does anyone have pics of any silver vests/ties with ivory shirts??? If my bm dresses are a dark celadon green, what are my options, other than green? Help...I am so confused!!!!

TIA!!!!
