I wonder if you can help me with a similar problem.  I think the fix will be different.  I have set the Accent and Highlight colors to green and the Appearance as Light in my Mac OS. I can see these colors as I navigate my MAC OS 13.2.1 as well as in Quickbooks Mac Plus 2024 V23.1.5 R6B.   When I see the green accent color in my check register I can see the transaction information (for example in my check register) but when I go to reconcile the account the accent color obliterates the type beneath it making reconciliation very difficult.  Of course the OS “highlight color” can be made lighter but the  OS “accent colors are dark and solid.   I have attached a sample of the OS “accent color” as it appears in a bank register and in the reconciliation screen.   Thanks so much for taking a look.
