Guess I could have looked at the back of the can for the number! It's marked '7771 Sand' and '20066 77718', so that's a match for the '7771830' on the web site. I was able to paint the gauge at a good break point on the face which minimizes the slight contrast with the original, and probably faded, paint. Of course you could also paint the whole part and get new a new lettering kit for the gauge. Once painted and installed in the dash, the gauge is far enough way from my eyes that I can't see any difference in the colors.
