I would love your idea/suggestions on what color combo to use on this cake.
The wedding colours are charcoal/grey/yellow. Flowers are white & yellow carnations.
I originally thought white tiers, with grey/charcoal/metallic shimmer ruffles and yellow gumpaste carnations. I'm starting to second guess myself now though!! The bride has no preference. Thanks in advance for your suggestions! (Original Cake Credit to www.justcake.com)

AI think you're spot on. At least imo.

If it were me, I'd make the tiers in a grey 1 or 2 shades lighter than the lightest ruffle. I'd make both yellow and white carnations. Actually, I hate carnations so I'd really try to talk the bride into letting me put yellow and white bows in place of the flowers but I guess that's beside the point, right ?

AThanks so much for both of your suggestions!! I'm going to do a trial tier today and decide. I also hate carnations, haha, but that is the only thing she really wants on the cake.

I vote for the grey tiers.
