Painting a Catachan army requires you to paint alot of skin, pretty much all catachans are dressed like Rambo with big toned muscles! So when i started on my army i had to practice painting the skin again. I knew how to do it basically from painting my Dwarf slayer a year ago, but i wanted variety in the skin colors. Since no human skin is the same, i wanted that in my army as well. Here is how the wonderful world of mixing colors, watering em down and ink comes in! Since i am mixing colors to get a smoother transition and i don't measure with any tools, other than my eyes, its bound to be slightly different colors(like real life skin).
Here is how i did when i painted Harker.
Now i painted Harker with relative few steps, cause i wanted him to look like he was really tanned. If you want your models to be brighter skinned either use lighter colors or use more steps adding lighter colors.
Here is how i painted the skin on my platoon squad commands medic.
Now i know i am not the best person in the world to paint skin, however i hope that i can help a few people getting a pretty good start. As all things, when it comes to painting, you take what you like and then add your own personal touch to it. As skin, none of us are the same and what some people like, others might hate. Just remember that if you like how you painted your models that's all that matters!
