As best I can recall from 30+ years ago, the original color was a pretty close match to Rustoleum Machinery Gray. The green tint comes with age and probably exposure to UV from fluorescent lighting and maybe exposure to oil. So if you want to match the current color, you will have to have the paint custom mixed. And no guarantee that it will still match a quarter century from now. My steady rest and tool post grinder purchased new with the 3996 and seldom used are not quite as green as the lathe. And my follow rest purchased about a year and a half ago is slightly less so.
