we're doing cobalt blue/silver. it's been kinda hard finding an exact match to the blue but it will be worth it in the end

White and different shades of pink :)

Purple and gold with fuschia accents

I know what you mean im constantly changing my mind on colors too.. I dont want the reception to look like a baby shower thats why im staying away from light blue and pink! :/  I have changed my mind like 50 times already! Frustrating...

I'm always changing my mind, too.  I started out with royal blue, green and sparks of yellow and now I'm considering the below color combination since we're doing a beach wedding:

we're doing Ivory and black, vintage inspired damask and lace, with shots of blood pink (a deep shimmer pink, without going into red) post pics as soon as I can.. :)

light yellow and light aqua, also white :D
