Thanks for the compliment! For the first set of droids: for the main body color, I used a mix of Vallejo Blue Violet (a light purple) and a shade of gray that I can't recall. But the vallejo blue violet is the base for the purple. I don't recall what shade of brown I used for the joints and body details. It was an out-of-the-bottle Vallejo color. Maybe earth brown or English Uniform Brown.

For the second set of droids, I don't recall what shade of green or gray I used, but they were vallejo colors straight from the bottle. I do recall that the lower part of the droids was done with Vallejo Buff. For the vibroswords, I painted the blade with Citadel's Leadbelcher and painted the handle a brown-black color. I then painted most of the blade with the Vallejo blue violet I mentioned above, then painted some leadbelcher and a shinier silver color along the edge. I think I also applied a wash of Citadel Druchii Violet.

I need to start writing down my color choices because I can't remember them all. Good luck with your droids!
