Do tell if it’s so easy to do.
What I said is correct: There are only two selections available in the Appearance combo box available in System Preferences: The settings you can choose from are Blue and Graphite.
The drab UI in OS X is miserable when compared to Windows 7. What’s worse, when I lower screen brightness to save battery life, the text on the window titles and window tabs in Safari... becomes completely unreadable. Dark gray text on gray backgrounds provides extremely poor contrast.
