Collar armor damage color

So I'm about to start working/painting this part. But I'm a bit confused....


I've see Rafalfett's stencil of the piece and it appears the marks that I thought were yellow (surrounded by the silver damage) but dulled by the airbrushing/weathering are actually grey? But on the Bulloch Fett build, they're yellow.

What color should I paint these marks??

It's definitely silver and dark gray, no yellow on there. That was my first impression too when I first made my ESB stencils, but then I changed to the right version. I recommend you not to use the JB suit as a refference (not because that suit is not awesome, but because never use a fan made replica as a guide), just stick to the ESB stills and screen captures.
