So I'm considering restarting my Tau army (long neglected) but the paint scheme took forever to do and probably won't switch over well to working with an airbrush. A lot of the models have gotten new casts, different base sizes, etcetera. Time to try a new paint job! The main goal here is to keep it quick and simple, something I can bang out miniatures at a rate of several a night rather than one a day. So I dug out an old Fire Warrior and gave it a go, but the paints I used didn't work together and I tried again on a Gun Drone with slightly different paints.
This is a total of 6 colors (7 if you consider the white primer and white paint different colors); White Primer (airbrushed), Vajello Heavy Goldbrown basecoat (airbrushed), watered down sepia ink, the Goldbrown again (lightly), a mix of White and the Goldbrown for the first highlight, and white for the second highlight. This is basically a MNM technique but I haven't got it down pat, but I'm okay with it.
A blue basecoat on the top followed by a lighter blue topcoat, and a red for the sensors and gun nozzles with a bit of white highlight.
I think I need to apply the blue before the sepia ink to get a cleaner edge between the yellow and blue, and I probably need a blue highlight, or maybe a ink wash in the depression. Other than that, I'm pretty happy. This is a trial model so I didn't go nuts trying to make the sensor look more lens-like. I can add more/different colors as needed, of course, but I wanted to keep it basic as possible.
For Fire Warriors, I'm thinking blue cloth/yellow-gold armor, and for Crisis Suits I might invert that - blue plates, yellow gold joints/limbs/weapons. Vehicles, wing sections in blue, the rest in yellow-gold. Thoughts?
