How to change the font type, color, size etc, of the text in Multi Rename interface?

[Raindrops]

I am facing a problem: In the Multi-Rename tool, whenever a file name is affected by the renaming rules, the filename is changed to light green.
It is difficult to see this text in white background.
Worse, when the filename is selected, the new name preview becomes totally invisible.

I could not find any settings to change the font (type, color, size, bold, etc) for the Multi Rename UI.

Can anyone guide me?

Thanks in advance!
