Wheel colour code

This may sound like a daft question but I'm wondering if anyone knows where I can find the colour code for my R105 JCW alloys? I know they're black but just wondering if there is a specific code for them, I have 3 gloss and 1 very annoying matte alloy. I've had issues before with getting alloys "colour matched" so would prefer the code.

Cheers :-)

Tried to have a hunt for codes but no luck ,you did get R105's in both Matt and Gloss Black

Thanks for trying, I spent a good while looking, might try on mini2! My alloys are meant to be gloss but one of them rather oddly is matt and not the the proper version, plus I bought a spare which is graphite! :-)
