Few months before, Gmail Themes were launched, Using which - Users could choose among the existing theme to be applied to their account. Now, Gmail Labs brings you another improvement in this feature that now you can create your own custom Gmail Themes by choosing colors of your choice.

To use this new feature, Go to Themes tab under settings of your accounr and you will find “Choose your own colors” option at the bottom of that page. If you haven’t activated Themes then you will need to enable it first from Gmail Labs under settings.

For Google Apps users- you will need to wait for some more time to see this feature in your account.
