How do I get this color? Anyone? If I start with red what should I add, or should I start with a chocolate and add red? Any suggestions would be great. Thanks!!

A little bit of black will deepen the red.

Just be careful not to make the icing bitter, try using non taste red from wilton, and even then the flavor can change, specially if adding black.... I personally made the decistion to not offer those dark colors on BC anymore ...

Starting with a chocolate buttercream or a whipped ganache helps get richer colors faster. The colors will not be true to what they normally provide, but they will be darker and richer with less color.
Just be mindful that the color will deepen and change as it sits. So, it is best to color little by little and if possible, let it set for an hour or so to see what the end color will be (when starting with white icing as well).

Thanks!

I usually do my colors the night before b/c they get darker as they sit, and even darker after frosting.

I use that color alot. I use Americolor Super Red, then add some Americolor Maroon to deepen it. It really comes out consistently the color I want.
