Google is all set to roll out this new feature over the next few days.Gmail Themes is a departure for Google, as they have not been known for offering anything with color and style. you'll find a tab named "Themes" in the settings page and you'll be able to choose from 30 themes. Google are also adding smiley’s to their Gmail service, in the hope of adding a bit of fun to their service.
