I cannot change the Gutter color on RSyntaxTextArea library

Question

Good afternoon everyone, I am not extremely experienced in coding, after long experimentation with RSyntaxTextArea I am still unable to change the Gutter. I cannot figure out how to code the Gutter Color, I would like to change the Gutter color to this new Color(9, 11, 16); Can someone please try to help me figure this out?

This is the library https://github.com/bobbylight/RSyntaxTextArea

This is my editor and the Gutter kinda ruins the vibe when I am changing themes

I found the answer, editing a xml file is not that hard.

public void changeStyleViaThemeXml(RSyntaxTextArea textArea, String path) {
    try {
        Theme theme = Theme.load(getClass().getResourceAsStream(path));
        theme.apply(textArea);
    } catch (IOException ioe) { // Never happens
        ioe.printStackTrace();
    }
}
