Change color of the tables in SlicerCAT

Hi,

I would like to change the color of the tables in a Custom App based on SlicerCAT.
I managed to change the color of the App with the palette in the QAppStyle.cxx file.

However, I still have a brown color for one line out of two in the tables that I am unable to change
Color tables

Does anyone have an idea how to control this color?
Thanks !
