With mammoth/mastadon ivory its grippiness(?) will depend on how much bark is left on. If it is heavily polished, ivory does not have a very good grip. If the ridges are left on stag it has very good grip, but is slippery when wet or slimy. Jigged bone has the same problem, but is not as secure when dry. These observations are my own and the opinion of others may differ.
As far as colours go, jigged bone can be any colour you want to dye it, so it can have a tremendous variety. Mammoth/mastadon/ancient walrus ivory can have stunning colors. I have seen ancient walrus ivory with different shades of red, blue, green, orange/yellow and brown all on a single piece. Stag is reddish brown to dark brown on the outside and creamy white underneath. It can be dyed, but only seems to look good in a very few colours.
I have not seen a pictorial reference on these materials. What I have done is look at thousands of knives or pictures of knives.
