Question on VP9 (and SK) colors: are there different tones of the grey, green, FDE? The grey seems mostly dark grey but I see pics of a blue/grey on occasion. Also, the "FDE" appears either dark coyote or what I'd call 'panzergeld', 'tank yellow' after WWII early armor tan/yellow. Green seems most standard. So, differing tones, or bad pics? Reason I ask is I'd like a panzer yellow VP9.
