Ok, so after I already started, I found some other posts online that say it's waaay easier to achieve black if you start with chocolate frosting. Well, I didn't, I started with white. And it's a very small amount of white....maybe 3-4 oz. To TRY to color it black, I used one whole shorter container of Wilton black gel, about an 1/8 of an almost empty taller Wilton black gel, and a HUGE heap from a newly opened container, and all I can get to is like a dark bluish-steely grey kind of color!! Should I just keep adding MORE??? Please help!! Thank you!!
