Found it Carl!

I dyed my fiancee’s over the weekend, and while I don’t think it came out perfect, she loves it. Even had a couple of purple splotches that you can’t really see in the pic, but she liked them because she thinks it looks a little like a slime stain.
I followed the recipie, except for that I couldn’t find the liquid orange, so I had to guess-ti-mate how much of the powder to use, and my machine doesn’t have a hot/cold cotton cycle, just normal, perm press, and delicate with the temps being hot, warm, and cold. I ran it at normal/warm everytime it was in the machine. I also used a bucket to do the dying in, and the rinsing in my tub. Thankfully, it didn’t dye the tub, but I don’t think it did a real good job rinsing it, due to their being a few purple stains.
But anyways, she was extremly happy with it, so mistakes or not, it all turned out great.
the white strip on the leg is where the hose connector is going to go, I gotta do that tomorrow. =o)
I am having trouble finding the purple RIT dye, do you have any suggustions about were to find some? Also I can not seem to find the orange liquid RIT dye either, both Wal Mart and Michael" s only had the sunshine orange.
If I’m not mistaken, the Rothco suits have changed color since many of these dye recipes were created. Something to consider before you go dyeing it with purple dyes and such. The purple was to counteract a greenish yellow tinge the suits had.
Rothco still uses the same fabric blend. This recipe isn’t even a year old.
The purple is there to counteract the yellow in the suit, which has consistently been the chief complaint against khaki Rothcos.
The orange is there because the RIT orange, after a washing in dilute bleach, actually becomes a great shade of muted reddish-brown, which duplicates that vintage khaki color fairly well when added to the de-yellowed Rothco. Alternating bleach and dye is fairly unorthodox, yes, and this result could be achieved by tracking down specialty dye shades, precisely measuring them, and carefully controlling the water temperature, etc., however, this method seems to produce the most consistent results with the most widely-available dye colors and plenty of room for error.
Check craft stores; they usually carry a wide variety of dyes. Failing that, try the detergent section of the grocery store. Strange place for dye to be, for sure, but many of them carry it. I haven’t tested Sunshine Orange, so I don’t know how different it is, but it may possibly work. You could possibly try it with red dye; just use half as much as you would have used of the orange.
The great thing about dyeing is that you can always adjust the color with more dye, or strip the color and try again.
Refer to a color wheel if you’re trying to offset a certain color. Good luck!
Yeah, I had a Rothco myself, and I ended up stripping and redyeing it like three times. 
Thanks for your suggestions. I think I will work on dyeing my Rothco jumpsuit after I come back from my family vacation. Also I purchased a box of pearl gray RIT to dye my pistol belt and elbow pads. What amount should I use?
you should use liquid black dye as gray will leave them too light.
Thanks for the tip about dyeing the elbow pads. Do I need to mix another color in with the black or dilute it with bleach to get the gray color from the films?
no
liquid black dye + hot hot water.
I just bought a Rothco and plan to try this:
1 Wash with Heavy Bleach, then soaking in hot water with salt and a touch of black dye (I"m gonna try edible icing dye in small doses. That stuff stained my mouth and teeth for 3 days.), then another wash with heavy bleach.
I’ll let you know how it turns out. What I’ve seen here works, I’m sure. I’m just wondering if there are simpler methods out there and the only way we’re gonna find out is to experiment with other methods.
EDIT: Well, my formula failed miserably. The bleach had a huge effect of making the Rothco even pissier, and when I tried the Black and Blue dye, it just wasn’t potent enough.
Fear not! I am taking pictures and have picked up some Rit Purple and Black. Once I find some Orange and some color remover, I’ll be making further attempts. I will not rest until I have my khaki backup!

whats the best recipe for color stripper?
the right is my old rothco with no dye, and the left is the new rotcho dyed with powdered orange, purple, and black. It came out too dark and i want to tone down the color so it looks more grey…it still looks tan in most light, b ut under camera flash its gret as you can see.
there is no recipe for color stripper. buy a couple boxes of it and the suit with it in a very hot wash.
and yes, color-stripper = color remover
i used the above recipe on tw and suits and seperate times nad one came out more purple than other..what can i do to combat that purple color?
my suit definately did not come out like the the other pcitures on this site, i dont know what i did wrong…i used the recipe step by step and mine certainly does not have the safe shade as the others
By the way, my finished product is my current avatar.

It’s subtle but much better and less pissy.
is the one box of pearl grey dye still work on the newer Rothco suits?
tried this today. came out an uneven purple. gonna try and strip it and start over. no liquid available, only the powder.
I DID order the tru-spec version anyway online for 30 bucks. at least ill have a backup. ive had this Rothko sitting around for a while, so if it doesn’t work out, ill strip it and just use the pearl grey(possibly from Joann’s or hobby lobby) instead of the multi color version of the recipe.
Just wear the tru-spec.
