MoD reader Andrew Perez writes in to point out that the BOHROK VA boxes all show an associated color of KRANA. If you look at any of the current eBay auctions , you can see that each box has a KRANA pictured in the lower left corner.

So, the colors are all as follows:

TAHNOK: blue
NUHVOK: light green
PAHRAK: dark green
GAHLOK: orange
LEHVAK: red
KOHRAK: light blue

TAHNOK VA: yellow
NUHVOK VA: black
PAHRAK VA: tan
GAHLOK VA: purple!
LEHVAK VA: dark grey
KOHRAK VA: white

So, barring any oddball exclusives being released, 8 shapes and 12 colors will account for the full 96 that I was told would be released. Now the only question left is where they hide these things, since none of the BOHROK VA pics I’ve seen show any KRANA hanging out.
