XE 'propeller' wheels

[mike020150]

Like most of us, I've found it impossible to avoid adding the odd scuff to my XE S's diamond cut propeller wheels. I have good intentions of attempting to tidy them myself so a key question is, has anyone managed to work out the official name of their grey colour? Jaguar uses different shades of grey on various alloy wheels so, without help, there's a high chance of me getting it wrong and buying the wrong paint! Mike.
