i had the lemon juice but not the extract so i just added more vanilla flavor! i bet you could add just about anything!
I make Rhonda's Ultimate all the time. I like to use the lemon juice because it cuts the sweetness a little bit. You do not taste it in the final product. I use 1 tsp of vanilla and 1 tsp almond for the flavorings. maimai16, try the mint, it is very good. I use it on alot of my chocolate rolled cookies. Rhonda's Ultimate rocks 
I have made dark colors like red, black, blue. I think it does alter the consistancy somewhat, but it is usable. For the royal blue, I color it to a fairly dark blue, then add a drop or two of black. I think it gives a nice shade of royal blue and you don't have to use so much blue. For red and black, I use Americolor super red and super black, you don't need so much. The last time I did black, I used Rhonda's Ultimate Chocolate MMF. It was fine, and didn't take much black coloring at all to get it nice and black. Next time I make it though, I will use both vanilla and almond, I missed the almond taste. I also tend to over color, stop when you think it isn't dark enough and let it sit overnight, it probably will be about the shade you want. HTH
