G'day,

I've never seen or heard of a red astral cord.

Silver, violet, etc, but not red.

Sorry, can't help you here.

But one thing I will say, anyone or any spirit communication that says 'in time you will know' most likely has no idea either. It is the mark of ego to give such an answer rather than just saying 'I don't know'.
