About background colors

If you use background image, like my backgrounds on your blog, you should adjust your blog background color as close as you can with the color of the center of the background image.

Even your background color is behind the background image, it shows a little while, before the background image has loaded. So if you have your blog background color close to background image color, all the texts and other stuff will be shown better, if the color is same with image background. And, of course, if there comes problems for some reason, that the background image doesn't show up at all, then your blog is still readable.
