Thanks all! I was considering that fluorescent orange, still available locally. @newday777, I tried to check out that store and it said the owner had exceeded the number of test transactions and should set up a real account. Weird vibes :| I think the thing to do is compare it to my new gauge faces, once I get them. I'll bring them with me to the local hobby store.
A related question, the black housings and the mount for the gauges need a fresh coat as well. Being as accurate as possible if I can. I see some debate around gauge housing being either semi-gloss that develops a patina to a nice satin over time, or that it was satin to begin with.

For the mount, I'm assuming that would be a semi-gloss like the frame?
there's no official color for the gauge cases. Honda "NH1" is black. Doesn't say satin, gloss, semi-gloss. So it's whatever one thinks matches.
This is a set of '75 550F gauges , the speedometer is NOS. The tach is one I "restored " using a new face and touched up needle. It matches the speedometer's case practically, if not exactly.
The paint is from Eastwood and is not a gloss, semigloss , or satin. It is between satin and semigloss .
I think it is the best match.
If you look at the glare pattern from the light reflected on the two cases, you can see they are near equal. It's a good test using reflectivity as a measure of equal "shine".
Hope this helps......my opinion.
I've never dealt with the mount color sheen, or a frame's official black color.
