So I have been using an old GW "ink" called chestnut ink for years now. Back when we bought it, the little jar cost only $2.49. I have been using it as a wash for Caucasian skin, it still works pretty well and I have enough for probably all light-skinned miniatures I will ever paint: The Liquitex (color: transparent burnt sienna) is what I use for bases. By mixing this paint together with standard brown and glossy black from apple barrel, I have been able to produce a nice muddy-effect on my jungle bases. But I am curious what the paint experts out there use for "inks" or "washes" to add a layer of color to the deep recesses of the models. I have heard a "green wash" would be good for ork skin for example, and I am also looking for some kind of "red wash" and "blue wash" for my future samurai armor project I have in the wings. An actual replacement for chestnut ink would also be helpful if I ever run out, so if anyone has a "brown wash" please let me know. If you have a certain recipe for your washes, or if you have a specific GW/other company ink/wash product, please let me know (links please!). Your advice is appreciated!
