Black and cream dress with colour run, and i have used dylon and colour run remover and it has not removed it? - colour remover

I have a vintage dress with black lace collar and cuffs cream. The black ran into the cream. I used to run the remover of paint, and not contributed to the problem. I've even done twice. GRR! All ideas, what I do now? Is there a home version can I do? HELP HELP!
