Rim color question

[Smallblock454]

Hi,

i have Carrera 18" rims on my Box.

Today i started to clean my rims and found some cracks in the paint of the inside of the rims. While investigating closer i found that the paint comes up from the rim.

Example:


So i decided to cut in and got a big paint chip not connected to the rim.


So i sanded it, primered it and than i found out that the color on the outside of the rim is different to the inside of the rim. On the outside Würth Felgensilber fits very good, but on the inside the paint looks looks a light primer grey.



Does anybody know the color code of that light gray primer looking color?
Or if there is a equivalent color available like the Würth Felgensilber for the inside of the rim?

Thanks & regards
Markus
