Strange leaking on driver side cabin

Perry1023

So there is some leaking inside the cabin and it appears to be coolant. I recently replaced the heater core and no leaks were present. Heater works and ac blows cold. The fluid is not clear and can detect anti freeze. I have inspected the fire wall for leaks, pulled back carpet, checked heater core connections. Nothing. It is the strangest thing. The fluid leakage is not heavy, just enough to dampen the carpet. Does anybody have and idea where it could be coming from? Thank you.
