When viewing web pages using Google Chrome, the color scheme can be inverted or set to contrast. This is not a built-in feature but an extension by Google can enable this. Download and install High Contrast extension from here.
Once installed, it will show up next to the Chrome address bar.
These color schemes can be enabled or disabled using keyboard shortcuts too (Shift+F12 and Shift+F11).
Webpages automatically are rendered in an inverted color scheme. This can be changed to any of the other ones like increased contrast, grayscale, inverted grayscale and yellow on black.
This extension can make viewing webpages a lot easier.
