Silky deep colored bbq sauce recipe?

The color is easy, first step is your rub, adding paprika to it, is the easiest way to set some red tone into the outside. In the sauce, using molasses gives a nice dark color and a nice flavor, worchestire sauce is also common. Other flavors that may or may not work with the rest of your flavor profiles are soy sauce, balsamic vinegar (preferably reduced first), chipotle sauce, etc. You can also add a fruit element or cola, this is all trial and error though, I used root beer in my last batch and like it alot.
