SEM ColorCoat Flexible Coating # 15303 Graphite is a dead on match and very durable
For the gray fairings parts, I've used SEM brand #39213, Honda Gray
The following paint is a perfect match for the ST1100's rims:
Dupli-Color # TY 01605 Antique Sage Pearl
Comments by Bob Peloquin STOC #3445:
I tried to find the wheel paint mentioned, Dupli-Color # TY 01605
Antique Sage Pearl at local auto parts stores. They had it only in
the touch-up bottles and I needed a larger area.
I went to an auto-paint distributor and they looked up the Dupli-Color # TY 01605
Antique Sage Pearl and matched it to 2000 Toyota color 1B2.
Their paint chip book showed that it was FAR from a good match.
They used their paint identification camera system on my front wheel
to determine the exact color it really was. It turns out to be a
standard Honda automotive color, coded JE5636 A Silver Stone. I had
a 400 ml (13.5 oz) spray can made up for $14.99 which should to
touch-ups for my bike and all my friends for the next several years.

Comment from David Wooster:
The black '91 code differs from the later black code; it is NH1 instead of NH1Z. The difference may have to do with the use of lacquer-type paint for the black '91 whereas the later models, such as the black '94, used urethane-type paint. This would affect your entries for '90 and '91. But it would not affect the actual color of the paint because to a painter, there is only one black color, as far as I know.
