Smoke is the only \"Transparent\" I have and it\'s good for the following:
Adding shadow definition to hair,
Adding shadow definition to fur,
Adding shadow definition to Leather,
Ok I\'m being silly there but you get the general Idea. It\'s a very dark brown \'paint\' which really has to be thinned to a very high dilution to be effective.
I have used it to good effect on my Chaos Beastman (51580) as an overall tonal wash once the two initial coats and highlights were applied.
You can use it for a complementary colour wash over the likes of Dark Angel green to get a leathery effect on Orc (Ork) skin rather than the standard GW colour combinations.
