What's everyone's opinions on frosting coloring? We've got a pretty good idea of what kind of cake design we want: 3 tiers with a spackle buttercream finish with loads of buttercream roses everywhere (because hell yeah, frosting). But we both think that looks super boring because there's no color.
I'm not a huge fan of pastels, especially because our wedding is in the evening and I'm wearing a dark blue dress (aka not pastel). But my partner is worried that heavily-dyed frosting will turn people's mouths colors, and my family seems to have a weird genetic ability to taste frosting if a color is too saturated (I'm telling you--if you buy me a cake from the grocery store and it has red frosting, I won't eat it).
What do you all think?

Re: Weird frosting color question
I guess I would vote no color, because:
1. Certain colors would make me think it was a flavor other than vanilla (like green frosting=mint to me) and I would be disappointed to have plain vanilla.
2. Colored frosting makes me think of kids' birthdays and supermarket cake.
But I'd still eat colored frosting because CAKE.
I think buttercream frosting is a perfectly lovely color by itself, especially if you don't want anything too fancy. I would definitely worry about food coloring staining people's mouths, and I can taste excess food coloring too.
My grandma and I are planning to DIY my cake and I will probably just frost it with plain buttercream and a couple little fresh flowers or other embellishments here and there.
ETA clarity
Example:
Fondant is 100% edible, there's a chance your baker might make their own which tends to be delicious. You could add a fondant ribbon around the base of each tier, add sugar flowers to the cake, you can even have a bride and groom topper modeled out of fondant. Your baker should have lots of suggestions for you
And/or you could add a little coloured frosting detail via piping or something. Examples:
Another option is to add coloured ribbon. Examples:
However, I think you could have the cake without any added colour and the cake could still look great. Examples:
I do think the ribbon, which would be removed and which wouldn't affect the taste, is a nice touch.
Thanks for everyone's feedback! We did aaaall of our cake tastings today, and we've already decided which bakery to go with. We're going to keep the base frosting white, with kind of diagonals in the frosting (sort of like the photo), and we'll either have frosting flowers or rolled chocolate flowers all over the cake in different shades of light blue.
