Max Alekseyev the highlighted field is in fact an editor component, it uses colors from the Editor color scheme. Selection color can be changed via IDE Settings | Editor | Color Scheme | General, Editor, Selection background property.
Please note that changing it will affect all the editor components, such as the main code editor, terminal and run/debug console.
Yes, working well. Underscore ‘style’ irritate a little but not critical
You can change the color of the underline or remove it completely by customizing the corresponding properties in File | Settings | Editor | Color Scheme | General, Errors and Warnings. I believe the one in your screenshot is either Warning or Weak warning.
Yes, I know, thanks. I was so happy that it began to work that tested everything 😀
Weak warning underline removed, thanks! Not critical but irritate
