3.5mm Jack cable colors?

Trying to repair a pair of HS50s with a damaged cable, It's a long story but basically I don't have the connector end of the cable, so I don't know which cable does which when soldering a new connector, I know it could be tested but I've had trouble testing, likely because I have pretty bad trembling on my hands so holding the cables in place to test is really hard.

Does anyone maybe have a broken pair of HS50s they could test with? The cables on mine are Green (wrapped in copper), Red, Pink, and Blue.
