Blue and Silver - and purple?

Hi,
I need some help with this. I would really like to change my colors from the ceremony to do the reception. i am doing a winter wonderland theme with the branches and the the lights...but I don't think I want to do the same for the reception. I would like to add a pop color which is purple at the moment, but how do I incorporate that without it looking like 2 different weddings?

I was thinking of adding a little purple to the BM's bouquets, but I don't know how to do so for the centerpieces. Any ideas or pics would be greatly appreciated.

TIA

I don't have pics yet but my colors are similar- blue & silver and fushia.
For the centerpeices (in my album) we stuck with whites and ivories, but tossd in pink wax flower, which is small and colorful- More like a filler. But it blends the color in nicely without being intense. I left the blue out entirely (BM dresses were really enough).

I'm also using different colors for the ceremony and the reception. I'm doing softer, subtle colors for the girls flowers and the huppah (pale pinks, creams, whites, peaches). Then, warmer, vibrant colors for the centerpieces: bright peaches and even a bright orange here and there. With the lights turned low for the reception, my florist thought it best to brighten up the flowers. Plus, I'd like the girls to stand out. Both sets of flowers will use green hydrangea as a base, so there will be some overall consistency.

I LOVE your color combination for a winter wedding. If you chose one flower in a white or other neutral to use as the base for both parts of the day, you can highlight the blues for the ceremony and the purples for the reception...

Sorry so long and hope that makes sense...
