Do I just add a tiny bit of brown to the white icing for off white? Can't think of anything else.
If you use brown vanilla instead of clear vanilla, you'll get an off-white icing. You could also add a bit of Wilton's ivory color, which is a light yellow-brown color.
Or cream from sugarflair, works like a charm!
Depending on your bc icing recipe, you can add a ratio of unsalted butter to your recipe for a light ivory/champagne color.
I have a 6-qt mixer, and use 4 cups of hi-ratio shortening and 1 cup unsalted butter. For liquid I used reconstituted powdered coffee creamer. It's a delightful creamy, non-white, bc in it's natural form . I get so many compliments from it.
