Look at the cover of this:

same colors but looks difficult to/for me. Good Luck!

when i heard[read] those colors the first thing i thought of was the ocean. You could also do a tiered cake with a blue base, and white roses with black edges of the roses. Good Luck on whatever you choose!

What about white background with black and blue interlocking rings placed randomly all over?

How about cake with white icing, with a black basketweave about half way up the sides of the cake, and then cover the cake in blue/white daisies....

You could do a combo, since it's for a wedding... for the guy... you could do a sheet cake iced to look like a tuxedo and put a blue flower on the lapel...
and for the lady, use a heart shaped pan, and ice to look like the top of a little black strapless dress and you could put blue ribbons, a "saphire" necklace or a corsage on it.... tie the two together with a big blue bow or something... even a bouquet of white/blue flowers

ok........ how about this... I found a cake with black on it... just add some blue roses, and you should be good to go....... have a look
