I am doing a wedding cake for summer - white fondant/yellow swiss dots/history blue ribbon/yellow&white gumpaste ranunculas.

I would like to surprise the bride when she cuts the cake to have varying layers of cake color. But aside from yellow and white.....not sure I want to add blue....idk.....need some creative minds from CC to help me out!

Here is a photo of a rainbow cake done by Omnicon. You'll be able to see the effect of colors on cake batter:

Does the bride KNOW about different cake colors? Since it is her wedding, I'd suggest you run it by her first before surprising her on wedding day.

yes, bride is actually my nephew's fiance! she is letting it completely up to me.....thanks so much for the site!

You are very welcome!
