Using CSS filter invert function I was able to make a really quick "dark theme" for Chrome dev tools. Some elements needed to revert back from being color inverted. List of elements that are required to revert back maybe is more than what I've found. Please let me know if you see any unusually colored element after applying this theme.

You can also "config" your source code colors using hue-rotate() or brightness() function at #-webkit-web-inspector .source-code selector.

Replace the Custom.css file in your "User Stylesheets" folder. Here is how to find Custom.css:

• Mac:~/Library/Application Support/Google/Chrome/Default/User StyleSheets/Custom.css

• PC: C:UsersYourUsernameAppDataLocalGoogleChromeUser DataDefaultUser StyleSheetsCustom.css

• Ubuntu (Chromium): ~/.config/chromium/Default/User StyleSheets/Custom.css
