How deep is the black compared to the regular bead blasted R1 would you say?
Although the I named this case SKB2, this GB should not be understood as second round. SKB2 keeps a few prominent design elements that were present in SKB1 but apart from that too much has changed to call it a "round 2".
The black of the SKB1 is something very different from the SKB2 black. SKB1 was made of aluminum, SKB2 is steel. SKB1 was anodized, SKB2 is powder coated. Black from anodizing can vary a lot, sometimes deeper sometimes not so deep. The prototype SKB1s all had a relatively deep black anodization. Sadly the production SKB1s anodizing turned out to be not that deep of a black.
A RAL color does not vary, you always get the same. All RAL colors also have a name, the name of RAL9005 is "Tiefschwarz", that translates to "deep black". It is the deepes black from the standard RAL colors.
You can get the associated RGB values here. I think it is a really good match for GMK-CR, which we know as base color for common wob sets.
