Got bored of the boring Gmail looks? You can now switch to one of the 30 themes available through the Themes settings.
From the most boring look to the extreme colorful ones, there are plenty to choose from to fit your mood and personality 
You can change your Gmail themes through your Settings page:
Just on the top right corner there
You can then select from one of the themes and Gmail will change the look straight away.
Plenty to choose from

Yesterday i changed my theme. Its great to see gmail in different style. And also if one wants to open gmail in office and want to disguise can use some funky theme

The big G is getting a little crazy in their old age!
I noticed things looked different but did not really have a good look at the new options. In all honesty I forgot about it. Thanks for the reminder, I will go and play around with it. I spend so much time in GMail, a new look could be quite refreshing.
If you spend lots of time in GMail, a fresh new look is always good, Lyndi
I usually pop my message from Gmail to my Windows mail client, so I don’t spend time much on Gmail, except for checking the spam folder
@Printers : LOL, I think about that too.
Well they’ve been so active lately in all of their range of services/products. It’s good for us
