68 mustang interior dye

I have a 68 mustang with maroon interior, my cousin owned it for years and I helped him restore it several years ago, and in the process we dyed the dash pad with some maroon dye and it matched perfict. I don’t know where he bought the dye and all the mustang places that I have tryed just have red dye. Do you know where I might find this maroon dye. thanks
