Gmail is starting to support personalized skins

Gmail is redesigning its pages today. The main body is still in the color tone, and the entire interface looks more sleek. The font color is lightened, and the title bar and border of each component are deepened. Reduced differences in the title bar and borders of each component, which makes Gmail look cleaner and more comfortable

A more important change is the start of support for personalized themes (also known as skins =). =).
