hmmm. This is interesting. I'll get to why it's interesting to me in a minute. Anywhere that is written down? My GM printed sources say something different. Of course, if yours has something else, I'm all ears. You have way more info than I do.
6/1987 Parts book shows 83 and 84 W40 with p/n all their own for the rear trim. 83 trim was p/n 22520449. 84 HO rear hood trim is p/n 22523747. It also shows this part number in the 84 Oldsmobile K47
Hurst/Olds release dealer bulletin, although I can't seem to locate mine at the moment.
6/1991 Parts book says G47 w40 for 84 uses the same p/n 22506643 rear molding as the regular G47 but it says paint to match - silver. Kinda makes sense. Ran out of the correct part, now have to paint the standard part silver.
Here's my "interesting" part: I originally believed my 84 came with a plain anodized aluminum molding from the factory because everything else on the car was original when I got it, best I could tell. The rear hood molding was dull and you could tell it was in sad shape. So I put a new plain one on when I got it repainted. Honestly didn't look that close at it when I chucked it to check for any "hidden" areas of paint or coating or whatever. I didn't know much about the 84
H/O until I actually bought one so I didn't know. Then I caught hell at the HO meet first time I brought it for not having it painted silver. Well, OK, not hell, but I was told by no less then 5 different people throughout the weekend that it should be silver. I then got to thinking maybe the paint just wore off the old one? Or maybe it was supposed to be bright molding? Unfortunately, I’ve seen them both ways at that meet, and TBH, I haven’t given it much thought since. The original wipers on mine were all silver instead of black, but the RPO is on the SPID says they should be black (C18). So they got painted black. The paint was in sorry shape when I got it so who really knows. It was one coat of chalky lacquer, so I'm guessing it was original paint. The decals were thick like the repro kit I got from Don Hartmann, so I know they were factory type on the car. Don's kit was the best repro stripe kit I'd ever seen, although it was a hair different than the factory stripes. Not much, and probably couldn't tell unless you seen them side by side.
I couldn’t find anything specifically stating the color of the molding. Except for the separate 84 W40 entry in the 1991 parts book stating it.
So, based solely on the parts book information, I painted it silver.
Using logic on a GM car, which I know can be scary, I surmise it should have been painted body color on the W40 cars since they have no rear fender moldings and skinny outer belt window moldings. Being a Calais, they should normally have the bright wide belt moldings and rear fender moldings as well. Unless they didn’t change the RPOs to reflect removing the moldings. I'm guessing the fact that B85 (wide belt moldings) wasn't included on the 84 SPIDs, so, perhaps it was a default setting for the molding delete meaning that they did it in reverse: if the RPO wasn't there, the B85 and the corresponding rear fender trim pieces were left off and the fenders didn't get punched.

From the 6-91 parts book. I'm guessing since the 84
H/O trim came pre-finished, and the old part number was unavailable, next best thing was to paint a standard bright molding silver.

And here's that ultra low mile T-top 84 someone was selling last year or something. It was so nice I ALMOST pulled the trigger on it. This trim looks silver to me as well. Am I not seeing something? I'm not thinking they would have painted it. 🤷♂️

If you look closely, you can see the paint line bump in the wheel arch red part of the stripe where black meets silver underneath. Typical for these stripes.
