I decided to paint up my Tau with as simple and quick a paint job as I could stand, without being too embarrassing.
So here is my Tau speed painting technique.
I wanted to do a simple tan and black, with as few steps as I could get away with. I removed flash lines and based with sand.
1. Black primer
2. Yanden Darksun foundation paint on the armor. This is the most time consuming part but it gets faster with practice, and the foundation paint covers nice in a single coat.
3. Quick hard outline edge highlight with Skull white ( if you want a more muted highlight use bleached bone) and red dots for the helmet lenses.
4. Gryphonne Sepia wash
5. Second Gryphonne Sepia wash. Be sure that the first coat of wash is completely dry before you add the second coat.
The second wash really knocks down the edge highlight and adds some depth. All that's left is to paint the base, and I will add some unit marking details later.
I used the same technique on this Crisis Suit.
Here's a family photo with the bases finished.
I hope that this helps me paint up a good amount of Tau, with a few color changes you could use this to paint about any armor.
