OK, old Res-C handled SR's are almost always black over black. Sometimes tan over tan. VERY RARELY satin.
Of the micarta SR's, black is still king. Tan is likely a runner up. Green is way back.
Now the LATEST SR's (Rat Warden, Ratmandu, Chopweiler, etc.,) the usual suspects of Busse-family colors came around. So you could nab a green or sage or tan or sometimes muddy.
Muddy tends to be a special-release color. I want to say the first blade to have it was the Mud Razor (Busse Hell Razor cousin) back in . . . 07? 06? I've got an M6 in muddy. They were pretty rare vs. black in any case.
As far as #'s - no one knows but Jerry & Eric. As far as rare-ability, depends on the knife. What do you have in green and muddy?
