2015 Gen1 Explorer Wheel Colour.

Hi all,
I have just washed my bike ( 2015, Gen1 Explorer) and noticed that my rear wheel has a tiny bit of paint just lifted from it. I have looked for the colour online but only find old posts. I saw that Vauxhall Metro blue metallic was the closest but can't find that anymore.
Any know it have experience of the best colour to touch up with?
Would be very grateful if you do. Want to stop it and touch it up before it goes any further.

 

Bought a can, will apply today and see how it turns out.
Thanks.
