You could go with Tan or OD green or an orange or red of some sort my Dad has an old full serrated Endura with a full red FRN handle with the molded in pocket clip. You could send us forumites an Endura and Delica in FFG for testing purposes
. I myself would like to see a Tan or Coyote Brown or as Lycosa has been saying on the Para models for a Recluse Brown a desert sand would be nice.
