So I didn't know where to post this, since it's about colors, which falls under wedding attire, decoration and invitations, so this is where it fell!
I don't know if this has been posted, but I found a website that is used for palette design - and it's awesome! It can be used for other things, like decorating your house, picking flowers for a container pot, etc, but I used it for my wedding.
It's basically a design tool that let's you drag a color wheel and once you are set on a color you enjoy, it pops up with complimentary colors that work well with the color you choose. Pretty cool. Then you can alter and go warmer, lighter, etc.
Love it!
