Nissan has now put names to the LEAF colors on the website. Prior to this, they referred to the colors generically. A little digging has provided the following info so that you can check these colors out at a local Nissan store:
Super Black - available on:
2010
Altima
Maxima
Murano
Xterra
Frontier
Rogue
2011
Versa
Sentra
Cayenne Red
2011
Rogue (should be on dealer lots soon, if not already)
I think it's coming on something else too, but not out yet
Brilliant Silver
2010
370Z
Murano
2011
Versa
Sentra
Altima
Rogue
Glacier Pearl
2010
