Steps to reproduce the problem:
1. Write an Android application which will load some html text using native webviewclient.
2. Go to Settings -> Applications -> Application Manager & select Android System WebView. If Device has Android Lollipop or earlier and has the option Uninstall Updates, uninstall those updates.
3. Launch above step 1 written application and check the font color. 
4. Go to google play store and update Android System Webview and relaunch the step 1 written application.

Font colors will have significant difference. With update, font's sharpness will be more lower than without the updates and harder to read.

* If device default OS is Android 6.0+, then this issue will be available without any updates in Android System Webview.

What is the expected behavior?
Font color/sharpness/weight should not be changed

What went wrong?
Font color/sharpness/weight is very lower in updated version of system webview and harder to read

Did this work before? Yes This issue was noticed with recent updates to the system webview. 

Chrome version: 51.0.2704.103  Channel: n/a
