Material Incognito Dark Theme
Updated for the new Chrome redesign! Please update to Chrome v69 for full compatibility with this theme.
Incognito mode currently uses a dark colour scheme to distinguish it from normal mode. This theme imitates that colour scheme and applies it throughout the whole browser.
Install the theme from the Chrome Web Store here.
This theme is fully open-source under the Apache License. Check out the source code on Github.
Chrome theme devs currently have no ability to colour the omnibox. As a result, the omnibox will always be white.
