Aux cable connection

[Softy]

I need to wire 2 aux cables, 1st Aux cable has Red, White and Black cables inside and the 2nd Aux cable has Blue,Green and a RedGreen mix. Which cables should I connect?

No idea. How about describing WHAT (or WHY) you are trying to do?

Just so long as you are consistent at both ends it doesn't matter which wire you use for what unless one is a shield wire. That would always be ground -. Otherwise the standard pattern would be:
Red would usually be right plus
White would usually be left plus
Black would usually be common ground -
