I have to totally agree with almosthismrs, go with wut ur heart & mind tells u! If u keep leading back to these colors then it's probably a sign! The colors blend together very nice so u can't loose on the palate. Don't get overwhelmed by the multi colors, u can have a beautiful wedding without color overkill! Just remember to be subtle when infusing ur color scheme throughout the wedding.
Btw, I love it.
