[QUOTE=HarryT;3591933]"Midnight Black" sounds as if it's probably black, don't you think?

You may be right. I always think of the color Midnight as in Midnight Blue.
Fabric covers are available in Charcoal, Indigo, and Sandstone. The Charcoal looks nice and saves $15.00.
EDIT
I just noticed from your post and confirmed online that the US site calls it Midnight and the UK site calls it Midnight Black.
