But Jeff! Was lavender correct for my Shelby?? It would make my wife happy?? She's beautiful and Irish and usually gets her way? So now it's in your hands most awesome expert"! 😂 ( we need a little more humor on our site)

Been gone all day but have waiting until I can check my notes and pictures others have provided over the decades and as in the past IMHO there is not enough solid info to suggest with any certainty what your missing color would be. It would be great if we had all the answers but at times we don't. Consider that you can wait and apply the third color at a later date and also consider that if you add one that you are not certain of you may lead others to copy and reproduce the same on their cars. This is how some things get started 

Sorry - don't have all the answers - guess none of us may
