Purple and green actually sound really nice! When I first imagined it I thought on no poor @krisdaversa but I googled it and saw some reallllly pretty images!
Our colors are light pink and tan. Beachy and romantic!
I love lime green! I wanted it to be in my wedding colours but no one else seemed to think that was a good idea... I agree with EV that if you use the lime green as an accent and the purple as the main that it will looks awesome! You may also want to think about peacock inspired weddings.. they use the purple, lime green, and a little bit of turquoise... either way you'll be able to pull it off beautifully!
Lime green and purple are very nice together after looking around I was starting to come around to it.....now my groomzilla has changed his mind because since we are getting married in January he feels that having bright colours like lime green and a brighter purple may be hard to pull off since are bridal party/guest will not be tan and be super white (his sister and my MOH look like ghost).
So he has now changed his mind to coral, aqua and golds. So we will see how long that one sticks for. Lucky for me I have some time :-)
