Hey @gunslinger387 ,
The comments above from @Casinostocks are spot on (as always.

)
One piece of advice I will offer is to order extra scale sets at the time you pre-order a knife (or later when a model you have is currently in production.) The price for the extra scales is very reasonable and it gives you options down the road if your tastes change or you somehow damage the scales that are on your knife. You can always re-sell them quickly later if you decide you don’t need them.
I have ordered extra scales for every CPK knife I have since I first got onboard. That worked out well for me when I went from an AECM craze to a TeroTuf focus. Who knows, six months from now I might go back to AECM again.
The recent photo below shows my spare handle sets. The burlap FK2 scales on top left the reservation when I sold that knife. I have two spare sets of UF scales inbound this week even though I have not yet received my pre-order knives. Like I said above, order your extra scale sets when the model is currently in production to insure availablility and best selection.
Getting back to your original question, TeroTuf is the most gray followed by unbuffed black canvas micarta. The two sets in the center column in this photo are unbuffed black for reference.
One thing I want to bring to your attention is the fact that the unbuffed scales are going to be more prone to absorbing stuff and darkening over time and use.
The EDC pictured below has unbuffed green canvas micarta on it. It was an ugly light green Crest toothpaste color when it first arrived. 2+ years later it is dark green from absorbing all sorts of dirt, grime, sweat, hand oils, etc. Even after thorough cleaning with dish soap and hot water or isopropyl alcohol it is never going to look like new unbuffed micarta again. The standard buffed micarta is more color stable in that regard. Something to consider.
Buy some spare scale sets. You won’t regret it.
