I really like the "Humane Studio" theme by Damien Guard for Visual Studio (you can find it here). Now working also with Spyderlib, I wanted to have the theme in that IDE, too. Even though Spyderlib does not provide as many customization options as Visual Studio, you can get pretty close:
You can set the colors in "Tools" -> "Preferences" -> "Syntax coloring". After adjusting the theme of your choice, you have to select that theme in a second step under the "Editor" tab as "Syntax color scheme".
Alternatively, you can navigate to your user folder, open the
.spyder.ini file and replace the following lines with new values:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
custom/background = u'#e3d5c1' custom/currentline = u'#eae4dc' custom/occurence = u'#fefd08' custom/ctrlclick = u'#259241' custom/sideareas = u'#edcfa3' custom/matched_p = u'#99ff99' custom/unmatched_p = u'#ff9999' custom/normal = (u'#000000', False, False) custom/keyword = (u'#2e53d1', False, False) custom/builtin = (u'#400080', False, False) custom/definition = (u'#000000', True, False) custom/comment = (u'#937a42', False, True) custom/string = (u'#259241', False, False) custom/number = (u'#007f7f', False, False) custom/instance = (u'#924900', False, True)
If you're following this approach, don't forget to select the custom theme as the active theme!
