I bought some Bionicle from eBay recently which contained quite a few Bohrok and therefore quite a few Krana. While trying to work out which Krana came with with sets I found an unusual one. I split them into 3 groups of Bohrok - Bohrok Va - Bohrok Kal following several guides from online and ended up with this.

Using Bricklink to define colours for the different sets, they are as follows;
Bohrok
Blue
Orange
Red
Green
Lime
Medium Blue
Bohrok Va
Yellow
Purple
Dark Grey
Tan
Black
White
Bohrok Kal
Flat Dark Gold
Metal Blue
Metallic Green
Pearl Dark Grey
Copper
Pearl Very Light Grey
I can't find anywhere that references a light gold krana. What have I found?
