Just did a run of Tactical Tailor ACU pouches, some miscellaneous origin ACU pouches, a USGI ACU waist pack, along with a complete ACU field uniform (Ranger cap, Coat, Pants, and under-armor combat shirt).
Used Rit Apple Green dye; results still drying, but MUCH more promising than results obtained using Rit Dk. Green Dye. I thought the light-colored pixels were a little too yellowish-green on the nylon pouches at first, and hung them on the clothes line to dry in the sun. When I looked up at the sunlit pouches, and realized that It was very hard to see them against the sunlit trees behind them, I reconsidered. The uniform, being of a different fabric, was overall darker, and greener.
My new standard is now Rit Apple Green dye for ACU, and Rit Dk Green dye for 3-color desert.
Pix in a couple of days, after things dry and I have some time.
