My FI and I went and picked out tuxes today. It was very easy picking out the black tux we liked. Then we came to the color of vest/tie. I took a swatch of the bridesmaids dress color to match. of course I pick the one color green for dress that they dont have

So now my options are go a shade lighter. Which far away can not tell, but close up can tell they are different. Or go with black vest and tie. My FI is wearing a white vest and tie, so it is just the groomsmen we are having trouble with. What do you think?
