Same here. Apparently the forged blue metallic is paint code PCG. This is the same as River Rock on the Jeep Wagoneers in recent years. You can see in person if you can find the right Jeep on a dealer lot. The STLA release last November 7 even listed River Rock as one of the colors. There's a chance it could be a different color on the Ram, but it's something to start with for now.
I don't see Steel Storm anywhere anymore. The STLA release mentioned Baltic Gray, another Jeep color, but that doesn't show up in the builds.
I honestly had hoped that since Forged Blue is in the build tool on-line, it would be available soon. I asked Ram Customer Care and a number of dealers, and it's a mystery. If I'm going to put this much money on a truck that I plan to have for a decade or more, I'd rather it be at least a little unique (as much as I do like the Delmonico Red - it's everywhere). So I'll be waiting a bit longer, too.
