I am currently writing JavaScript code in PyCharm, and I have noticed that PyCharm highlights JavaScript errors with a grey color, specifically indicating "Unresolved variable or type." How I can configure PyCharm to highlight these errors using a red color instead?
Press Ctrl+Alt+S to open the IDE settings and select Editor | Color Scheme | General.
Under Errors and Warnings, you find the Error option. There you can change the color.
