Thank you for the responses. Now, I have more questions regarding choosing the the right type of cake for sculpting. My wife wants me to make a simple yellow or white cake, ice it with a simple flavored buttercream, and fill it with a cream cheese filling. As far as the cake is concerned I was thinking about going with RCB’s All Occasion Downy Yellow Butter Cake, White Velvet Butter Cake, or the Golden Luxury Butter Cake. Would any of these cakes pair well with Burnt Orange Silk Meringue Buttercream? Will be able to tint this buttercream that deep red color as in the the link in the OP? If not, which buttercream do you think will taste good and work well with the application I would like to use it for?
