Help with wedding decorations?

I already have an idea of what I want which is a erfly/garden theme wedding and reception. I want the wedding out doors with white chairs for people to sit on but I want to accent them with something like flowers or bows in a differnt color. The flower girls will be wearing nice dresses with fairy wings and will drop pastel flower petals on the gr isle. I want the reception to be indoors but am unsure how to pull the whole look together. Light pink, purple, green, and yellow come to my mind when I think erfly/garden. I wanted to have flower centerpieces in light colors then a few flowers with a pop of bright color I also am going to put erflys in the centerpieces. I am not sure what color table cloths I was thinking light green but will this work? I want it to have a garden/erfly feel but also be clean and somewhat modern.. how can I pull this off? I want to have light colors but also a pop of color in some places. What colors should I use on what things?
