Oracle SQL Developer


Unfortunately Oracle doesn't make it easy to import a new colour scheme into SQL Developer, thus a little bit of hacking is required.

  • Close SQL Developer. This is important. If you modify the scheme file while SQL Developer is open, your changes won't be saved.

  • Locate file dtcache.xml in the SQL Developer's settings directory.


%APPDATA%\SQL Developer\systemn.n.n.n.n.n\o.ide.n.n.n.n.n.n.n


C:\Users\dracula\AppData\Roaming\SQL Developer\system3.\o.ide.

Linux or Mac OS X:




  • Locate <schemeMap> tag inside dtcache.xml file. Insert the content of the color scheme xml file inside <schemeMap> alongside the other colour schemes. Be careful not to break the XML.

Insert the contents of color scheme xml file after opening schemeMap tag

  • Launch SQL Developer. Navigate to menu Tools->Preferences, then select item Code Editor -> PL/SQL Syntax Colors in the left pane.

  • Select theme in the "Scheme" drop down list on the top.
