I'm pretty sure all the small truck '57 GMC gauges were a flat black with off-white lettering. Here is a picture of my '57 dash. The oil pressure gauge and ammeter are from a larger GMC of the same era and the tach is a re-faced Sun SuperTach II running in 4 cylinder mode so full sweep on my 347" V8 was at 4,000 RPM. The stock gauges have a green, clear plastic lens inside to make the gauge markings appear green at night with the dash lights on. The smaller truck oil pressure gauge was a 90 degree sweep. The ammeter position in the dash had a typical red "idiot light" indicating generator wasn't charging instead of the meter I put in.
Classic Parts still sells a reface kit for the 55.2-59 GMC instrument panel. Click here.
