change color of matching closing element

[NoamMuallem]

Hello, I am using you'r nvim config, I wont to thank you for the hard work, its my favorite setup, I have 2 things however that I can't change because I cant find where they are being defined..
where do you define the color change to the matching closing element like (, { and even jsx tags.
In addition where do you change the status line to show the line of the closing tag if it's offscreen?
Thank you again...
