Very simple Black Aero Theme with good contrast on tabs. Background tabs are transparent gray with back in focus tabs.
NOTE: In a recent update chrome changed something so the top tabs may not look how you want them to on different OS's. ChromeOS and OSX seem to have some of the odder looks now, but you might be happy switching between this theme and the other linked below. I will be working to resolve these issues/build an additional theme that resolves the issues once i can figure out that that issue is :D
Note: Due to many requests (and by many I mean like 3) i will make a few more versions of this theme with different Tab colors and what not.
One is all black tabs

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
