River Rock Green Mica bumper color?

[katchup]

Does anyone know the paint code for the bumpers for a 2001 River Rock Green Mica LC? Paint guy says online its one of three listed below, none of which are actually River Rock Green, which I thought was the color.
1D2 Grey - metallic/pearl
UCA78 Dark Taupe - metallic
UCA76 Medium Grey- metallic/pearl

Or is he just completely wrong? Pic of my new project LC100

That's the bumper paint code and or river rock?

Yup, as far as I know, bumper and body should be the same on this color unless it's been modified.

Super late but the code for bumpers and side moulding is UCA76 Med gray. In bright light you can’t tell the difference. Only the metal body panels are painted river rock green 1C3. I replaced the right rear moulding on this 2000 River Rock and per vin required the med gray, as you can see in warm lighting it does not match the metal painted surfaces but does match the bumper which has never been painted. Also included pics in different lighting where it appears to match. Pretty crazy, it gets more noticeable when you polish/correct the paint. Seems a neglected RRGM tend to match is all lights.
