Hi Jlux! Although I don't work at HM, there are several back colors that are not available yet. These other colors that are not out yet match the rest of the seat colors.
To quote Anna when I asked her about these other back colors and the H-Alloy base:
"The next set of Mirra 2 Butterfly Back colors (Twilight, Urban Orange, Alpine, and Lime Green) are planned for May 2014. The H-Alloy base is planned for June."
Hope that helps!
If you have any additional questions, please contact Herman Miller Customer Care at 888.798.0202.
