The purple is X2 purple and X2 Florida Grape blend. I think that was done in 4 ounces of Essential using 6 drops of purple and two drops of the Florida Grape.
The chartreuse is a dandy. I make this in 4 ounce batches for tails using the Essential plastic, ten drops of X2 Chartreuse and two drops of X2 Fluorescent green and one drop of X2 Bright Green, plus some blue hi lite. Pictures don't do the color justice at all, but the blue hi lite in this chartreuse makes the color turn a corner than can't be gotten with straight colorant.
