I've found the formula that gets as close to Magpul's discontinued Foliage Green as you're going to get with Rit. It's just a bit too green, but reducing the green makes it too gray.
4 cups of water for 3-4 minutes.
1 Tbsp Pearl Gray, 1-1/2 tsp Taupe, 1/4 tsp Camel.
The inconsistency in color is because I didn't manage the clock and water temperature as anally as I could have. The far right magazine is the one I did last night in Foliage Dark Earth (see below) re-dyed with the above mixture.
With the black of the receiver between the parts, the color variance isn't very noticeable.
In the process of figuring out foliage, I think I stumbled over a decent Magpul Stealth Gray combination.
8-minute soak. 4 cups water.
1-1/2 tsp Pearl Gray, 1/2 tsp Taupe.
1-1/2 tsp Pearl Gray, 3/4 tsp Taupe.
1-1/2 tsp Pearl Gray, 3/4 tsp Taupe, 1/4 tsp Camel.
1-1/2 tsp Pearl Gray, 1/2 tsp Camel. I call this one Foliage Dark Earth because it's got aspects of both colors.
|Foliage Dark Earth (L) compared with Foliage Green (R).|
|1/2 tsp Tangerine, 1/4 tsp Pearl Gray, 1/4 tsp Dark Green. This is Rit's official formula for Flat Dark Earth. It's too orange.|
|1 tsp Camel, 1/2 tsp Emerald, 1/2 tsp Aquamarine. This color looks closest to Foliage Green in Rit's color guide.|
|4 tsp Dark Green, 2 tsp Lemon Yellow. The next closest to Foliage Green in Rit's guide...|
|1/2 tsp Pearl Gray, 1/2 tsp Dark Green.|
|1-1/2 tsp Pearl Gray, 1/2 tsp Dark Green.|
|2-1/2 tsp Pearl Gray, 1/2 tsp Dark Green.|
