1. Go to your local craft store (I go to Michael's here in Sin City) and buy "Folk Art" Metallic {insert color name here} Pearl paints in the all the colors you plan to use. Also get the white and black in the same range. Get the same ink colors (I used "Higgins".)
2. Figure out how you want each figure to look. Always use colors that flow from one to the other on the color wheel: red to yellow through orange, blue to red through violet, that kind of thing. Start on one side of the figure, paint on the raw base color. Add alittle bit of the other color, closer to the center point. At the cnter point, you should have a 50/50 mix of the colors. add progressively more of the second color until it is pure at the other end of your paint pattern.
3. Carefuly ink all the seams and recesses of your model with the same appropriate color ink. I used red ink on my yellow bits. but otherwise everything was inked in the parent colr. It's sometimes a tough call where to stop with one ink color and start with the next, but with a little practice anyone can get the hang of it.
4. Now this is the tricky part. Take your base color on one end, and add the Metallic White Pearl into it, to provide a little highlight. Use this on the affected area, and a little bit more to the center. Now, add more Metallic White Pearl to it, and highlight the same area again, and also closer to the midpoint. Now mix your 50/50 midpoint solor, and add more MWP and highlight the middle area. Yet more MWP, and highlight almost out to the previous highlight zone. Repeat as necessary on the other side. Fiddle with this tecnique until it looks right.
5. Go back and touch up your inking, you have in all likelihood gotten some of your highlight color onto it by now.
6. Go ahead and finish up your bases the way you do every onther model in your collection. Or, you can choose something new and different to show off your originality with this army. The important thing is that every base in the army be done the same. With a huge array of colors and even model types, uniform bases really help tie an army together visually. And crap-painted models that are based well and consistently will look better as an army than beautiful models that are left on lousy or inconsistent bases. Because we're not painting to win any awards, we're painting to ahve an army that looks kick-ass on the table top, right?
7. You didn't figure out where to use the black? Go back and check out the picture of the Ambients. In this case, the black is just another color, not part of the shading or highlighting process.
