how to change the color of current active terminal title bar color when switching between tabs

Question

I am using ubuntu 14.04. I have to open multiple terminal tabs while working. As I open more and more terminal tabs, It is becomes very difficult to identify the current working tab. I like to know how to change the color (say red title bar) for the active terminal tab

Answer 1

What about this way?

1. Pick a color in http://www.color-hex.com/

2. Create a file

vi .config/gtk-3.0/gtk.css

3. Change the content of this like following

   TerminalWindow .notebook tab:active {
   background-color: #ffce00; // what you want(or pick)
   }
