I have a bride who wants a three tiered, multi-colored wedding cake. She either wants tiffany blue on the bottom tier, a light shade of blue on the middle tier, and white on the top tier. Or she wants me to fade from the blue to the white. This is a buttercream cake with absolutely no decorations except for a special topper they ordered. I'm looking for some photos of something similar, but I'm having no luck searching through the galleries. Can anyone help me out. Also, your thoughts on the two color options would be appreciated.

Here's one...still looking for you.

Now your question about the shade...I would match the topper or a blue that's being used in the wedding and go from there. I think tone on tone decorations would be pretty like dots, scrolls, or something like that instead of just totally plain. Maybe you can guide them.
