Mac OS X Lion Dev Preview 2 which initial appearance color was “Blue” bу default has already outed for the registered developers through the Mac App Store. Now it has added Graphite color in its appearance option. The first Developer Preview disabled the ability to adjust the window appearance colors, which led some to believe an entirely new UI would appear at the Lion public debut.
Along the same lines, several Mac sites are reporting that Lion is moving away from Aqua in favor of a more modern finish to windows, scollbars, and buttons. Apple has removed a lot of the aqua trimmings from drop-down menus, they’ve also taken the pill-shaped aqua buttons and given them a more flat, rectangular appearance.
