Hello
I have some custom modules where the background color is blue and the text is white. When I try to edit them, if I click on the text, JCE highlights the line with a very light background, making the text unreadable (white on white), and I can’t work on it.
How can I prevent this? Or how can I change JCE’s selection color?
Thank you

Hi

attached the result with High Contrast Mode enabled.
