re: 'White' SMBC?

Thanks so much cupadee & MsGF for the tips!! I’m going to make another test batch this w/e with Walmart brand butter and/or try adding either Wilton White White or a tiny bit of violet. I feel the need to test it because whatever I do to make it whiter, I don’t want to change the taste nor the texture (it’s super easy to work with – smoothing).

MsGF – wouldn’t using all shortening just make it American BC or are you saying just to replace the butter with the same amount of shortening? Won’t shortening effect the taste?
