Why is it blue green? Pgm recovery from cat converter/mlccs.

[Zemalo]

Hello, I’m currently trying to figure out why my solution (sample pic below) is a blue green cloudy color. The cat was a metal substrate cat from a 04 grand Cherokee. I figured while I was leeching it using the hcl - bleach method I’d try and leach the palladium out from some mlccs I collected as well. The solution has been sitting for about 24 hrs now and I think I may have added too much bleach. None the less I’m more so wondering why the solution is blue/green and why it hasn’t taken much of a red color that it would normally take
