After a solid 24 hours with Google+ we’ll admit we’re in love. Not only is the service a fresh twist on Facebook’s tried and true ecosystem, but the minimalistic white/grey/black/red UI is downright awesome. Now if only Gmail featured the same type of look…wait a minute.

Thinking that very same thing tonight we took a stroll on by the Gmail themes page and lo and behold, two new themes “Preview” and “Preview (Dense)” were waiting for us. The look is built to follow Google+’s UI finally bringing a feeling of completion to Google’s overall ecosystem.

Until today, Gmail was the odd man out as the dark header bar was not carried over into the inbox. That changes now, however.

As for the differences between the two themes — Preview (Dense) simply features less line vertical line spacing than the regular Preview theme.

According to the Gmail Blog, the new Preview theme is a small glimpse at what Gmail, and Google’s web services overall, will soon look like. We like it. What about you?
