Steps to reproduce the problem:
1. Open Chrome
2. Start your reasearch/normal browsing session. After sometime you will notice lots of tabs you've opened. 
3. In these kind of scenario you will be shifting between tabs and getting confused. A better way to handle this would be to have a different color for the last visited tab

What is the expected behavior?
