Note: This has been deprecated by >SciTE Customization GUI.  I highly recommend SCG for all of your theme needs.  Thank you.   and your SciTE customization knowledge too.

Here is a dark theme for SciTE for all you dark theme fans. I got this theme from Notepad++ which got the theme from the Dejavu font project (http://dejavu.sourceforge.net/wiki/index.php/Main_Page).

Customized by hand because the original themese aren't perfect. They had black text on dark background.

The line number margin, fold margin, editor, and console is themed!

I encourage you to post your theme too. Also, if you have any knowledge that would enhance this and any other theme then I encourage you to post that too. Please post a fairly high quality screenshot too please.

Instructions: (this works for me anyway. If you know a better method lemme know)
1) create the file named 'Twilight.SciTEConfig' in the 'SciTEConfig' folder found in the SciTE folder of your AutoIt installation
2) fire up SciTE and press 'Ctrl+1'
3) select the 'Color Settings' tab
4) click 'New Scheme'
5) select 'Twilight' from the drop down list
6) finally, click 'Update'
