Riff where'd you find reference to it in "Charcoal/Dark Gray"? The mfg website says it only comes in black and gray.
Whoopsy, I thought I had read somewhere on this forum that 3 colors were available. However; after clearing the cobwebs, I now remember YOU had created a custom half-n-half mixture using both 1-part Black + 1-part Gray to create a Charcoal/Dark Gray mixture. My bad.
