Help need ideas on how to 'summer-ize' my sapphire blue and amethyst/silver wedding?

It is very difficult to properly match blues and purples, especially when the dresses are going to be blue with silver. Blue/silver/pink is a nice combo....you could incorporate different shades of these colors..like lighter blues, more neon pinks to give some detail to the wedding. silver is a great accent to almost any color scheme! it will lighten the dresses and can potentially lighten the entire feel of the wedding. I have purple dresses and am using silver table clothes. i am also having hot pink goodie bags to go along with the candy bar i am having...the flowers are pink/purple/white and silver goes with all of them
