It's a complicated color.. I had a front and rear guard painted to match the tank a couple of years back, and the painter had a hell of a time getting the color to match. It's bang on now, but there was swearing involved.
It's more flat than matte.
The tank panels are the same shape as their brushed aluminum counterparts. I changed to those too.
Hey; sorry about the late reply. I don't have specific info as I left that to the painter who knew what was going on. I was only assisting, helping set up test pieces to get the color right. I recall it not actually having any matte particles in it, or some tiny amount of them to get it to match.
