How can I make Lime green with Wilton paste ? I've searching on the net and on this site to get a color mixing chart ...but no luck

I need to know ... if it's 2 parts lemon yellow to one part leaf green or vs.

bump bump ...

I made a flip flop cake the other day with bright lime green for the straps. Sorry, pics not up yet. I believe I used lemon yellow wilton brand to sky blue. Usually 3 to 1, but I would start light, do just a little and go from there. This made it more bright lime than the yellow/green combo.
