So keep that in mind when shopping for fabrics next time. I hope the other suggestion above helps you somewhat. But I wouldn't sell any clothing that had paint added to the dye.
I just came from Joann's and noticed some "Jacquard" dye for nylon fabrics above the RIT dye. I wanted to take a pic for you but I left my phone in the car lol.

I had no idea they sold acid dye at Joann's. Now I know!
Let us know what works... I'm curious now.
