DON'T USE RESEDA GREEN.
This colour is the export green colour for late 1930s to early 1950s and is a fairly bright green. The Colt green is very much darker. If you can't do better, PM me and I will contact someone who knows Colts through and through, not only their colour, and see if he would be prepared to help you. Chances are very high that he would want to.
