Changing the foreground color of a DataGrid row based on property

Hello Experts, hoping someone could show me what I'm doing wrong. Note: my code does run and I experience no errors AND code execution breaks in the Value Converter, but does not change the color of the cell as anticipated.

Overview: I am loading some pallets into a DataGrid. If Quality Control is completed I want the text to be black. If Quality Control is needed, then I want the foreground to be Red. Also because I have multiple bindings going on, I decided against using the ElementStyle and instead am trying to use a DataGridTemplate.

Any help would be appreciated.

Warm regards,
James
