Yellow, purple, and/or gold wedding theme?

My wedding is in June and the colors I love are purple (silk lavender) and yellow (bright). My only issue is the reception.I had two ideas- yellow or lavender dresses with purple LED room lighting. The venue is a little dark that is why I'm thinking of using extra lighting (LED wash, candles, centerpieces) to set up a romantic mood. I'm not sure which option would look better, plus what do I do for the table setting (table linens, chair covers, swagging, head table)? I was considering gold/champagne color because it's very elegant but on the other hand I'm not sure if it would work with either yellow or light purple/lavender. Someone please help. Any suggestion would be appreciated. Thank you.
