The best I can say that I have done
is to color-match the cam cover on my Lotus Elan, after the paint job which was more affordable due to the child labor involved ...
although I had to put the engine back in after the paint job.

Most of my effort was dedicated to getting all the wiring to work (not so easy on a fiberglass car with no ground connections)
Cheers,

At least I chose a good color!
