Paint code LA7C is correct for VW Moonstone Grey.
VW used to attach a data label including paint code details for the car to the boot floor or the spare wheel well, and a second copy of the label in the front of the service book or owner’s manual. However, with service records having gone digital there’s no longer a service book and I think VW owner’s manuals are also online now. I also think they’ve stopped putting the data label in the boot.
With those see-through paint pens, sometimes the paint can appear to be wrong colour in the pen and needs a really good shake for a few minutes so the agitator ball in the pen can mix the contents thoroughly. Once mixed, in case it’s the wrong colour I’d try it on a piece of white card first and hold it next to your car to check for colour match.
If the paint doesn’t match, that suggests a Moonstone Grey label has been attached to a paint pen containing something other than Moonstone Grey paint.
