This post is deprecated, please read updated this tutorial how to change the color scheme from .jar file.

If you are tired of the default look or darcula theme of IntelliJ (tested on 2017.x and 2018.x versions) or Android Studio , you can switch to a better looking theme . This is a very short process

IntelliJ with Obsidian.jar theme and darcula

1 Select your theme

color-themes.com has plenty of themes ( Sublime Text 2 , Monokai,) . Download the .jar file . Roboticket.jar is my current theme

2  Import the theme

Import to IntelliJ or Android Studio by going to File -> import settings -> and select the  .jar file you downloaded.
Select All . press OK. Then Restart your IDE.

Note : if you use darcula theme previously , you will notice the new theme is only applied to  the Text Editor. The light theme clearly contrasts

3 Appearance theme

On Mac , go to Preferences -> Appearance  . You can also use the shortcut Preferences -> search theme on the top left search bar
Next to Theme , Select Default . Or Darcula if you are using a dark theme .
Restart your IDE.

4 The final look

Roboticket.jar
