I'm trying to use a custom syntax highlighter, but I can't set the background colour.

This is wrong, how do I colour the empty background / white space, per file type not a global override?

  1. Click Settings, Style Configurator.
  2. In the right half of the pane for "Global Styles: Global override" click the color box next to background color to choose your color.
  3. Check the box that says "enable global background color"

    That will override it for all file types, is it possible to do it for only one?

    I don't believe so. This is the closest option for what you are trying to do.

While browsing for something similar myself, I've found a possible aid to this problem.

In the user-defined language style configuration menu (found under Language > Define your language...), you can right click the color panel, and it will become hatched. This allows it to simply use the default coloration for this section.

Unfortunately, I don't yet see a way to define a background color specific to a user-defined language.

  • @DavidPostill This is definitely the correct answer to fix one specific UDL in Notepad++, as requested. Brad's answer breaks Find result highlighting. Jun 9, 2016 at 13:25
  • @CeesTimmerman The OP says "how do I colour the empty background / white space" not the font background colour!

  • Indeed. The "syntax highlighter" part threw me off. Jun 9, 2016 at 13:42
