😧I just figured out I already asked this question. Opps! I was reading somewhere that power automate can include formatting in the expressions. All I could find was for date formatting, nothing about font color, etc.
I'm not sure if this is possible with Power Automate. However, within Excel itself you can show changes, and when you click on any of the changes it will highlight the cell that changed - this might be another option you and your team can explore.
