How do I change the background color in MySQL Workbench?

There's no universal way of changing the background color of MySQL, unfortunately. Having a dark background depends on your operating system and your version of Workbench.


Here's how to change MySQL Workbench's colors (INCLUDING THE BACKGROUND COLOR).

Open the XML file called code_editor.xml located in the data folder of the MySQL Workbench's installation directory (usually C:\Program Files\MySQL\MySQL Workbench 6.3 CE\data). Here you'll find a lot of styling for different code elements, but there are some missing.

MySQL Workbench uses scintilla as the code editor, and scintilla defines a few more styles that you can use in the code_editor.xml file. The one that is used for the background color is style id 32.

Here's the complete list for MySQL (scintilla has thousands of styles for many languages) with my configuration:

<style id= "0" fore-color="#DDDDDD" back-color="#2A2A2A" bold="No" />   <!-- SCE_MYSQL_DEFAULT                  -->
<style id= "1" fore-color="#999999" back-color="#2A2A2A" bold="No" />   <!-- SCE_MYSQL_COMMENT                  -->

MySQL Workbench 8.0 Update

Based on Gunther's answer, it seems like in code_editor.xml they're planning to enable a dark mode at some point down the road. What was once fore-color has now been split into fore-color-light and fore-color-dark. Likewise with back-color.

Here's how to get a dark editor (not whole application theme) based on the Monokai colours provided graciously by elMestre:

<!--

Remember to paste all these styles inside of the <language name="SCLEX_MYSQL"> tag in data > code_editor.xml.

It's not really a programming question, but it's a quick one so let me answer that. MySQL Workbench's themes are a collection of colors for certain main parts of the application. It is planned to allow customizing them in a later version. In order to get a dark theme as one of the templates please file a feature request at http://bugs.mysql.com. But keep in mind, not every UI element is colored according to the Workbench theme, e.g. text boxes still stay white as they use the Windows standard colors.
