I'm having an autumn wedding and my dress is going to be light blue. Do you have any suggestions for other colors that would coordinate nicely with it?

pale orange. It just goes together. Especially orange being a fall color. They're opposites on the color wheel so they contrast well together, making the other one stand out.

If your dress is light blue...for fall, try maybe some light colors to go with it, but to stick with a fall like theme, go with silver and maybe a light or pastel gold color.. Purples are nice as well. I hope this helps a little bit.

pale colours

maybe white, peach, pink, silver????

just some ideas
