i use the gel colors and when i'm adding the color i use a toothpick to dip into the jar and spread it on the icing..

BUT when you're trying to create colors and people say on the charts a drop or 2 drops...how in the world can you gauge that?

Does CC have a color mixing chart available somewhere?

for my WB cake I had to throw out an entire batch of what i tried to make fuschia....it was the weirdest color i've ever seen in my life! haha

Well, what i do, is color a cup of icing to the color i want then add that to the rest of the icing. If you color the cup a darker shade then what you want it will be fine when adding to the rest of the icing. As far as drops, they are probably talking about colors like americolor that comes in a squeeze bottle, for the pastes in a jar i would use a small dollop for each drop.
