Can I have separate themes for my wedding ceremony and reception?

My colors are turquoise and brown. I am using that for dresses I'm having made and the flower arrangements I making. I'm also making elegant tree branches with lights and ornaments for the ceremony. The reception, however, is themed as a tea party and we are setting each table up with a different tea set theme (japan, vietnam, garden, english, victorian, so on...) The problem is that that reception will have lots of different colors. How should I organize the two themes so that it doesn't look tered and unorganized?
