How do I put my colors together???

OK SO! lol I've decided to put my bridesmaids in a coral/peach. I want to decorate the isle with peach pom poms and I want to have little bells with a tiffany blue streamer on them.. I'm also going to make programs that will be ivory and gold.

Those are my 4 colors basically, peach/coral, tiffany blue (which I don't want to go overboard with) ivory and gold

Now is that too mixed up? I don't like to be too matchy-matchy but I also don't want the place looking like a circus.. then my table set up anxiety starts!

I want to have dark wooden flower boxes holding mostly white flowers with a touch of peach.. then I want my table clothes ivory/white and my napkins peach (if they have it!) but my favor boxes I was going to make them the light tiffany blue with a white/ivory flower on top..

NOW am I getting too crazy??

I also wanted a tiffany blue card box.. ay yi yi!

I feel like I just CANNOT visualize until I see it all together..

what do you ladies think??
