After a page loads the colors are right, then it suddenly turns light blue and the text fades to gray

When I open google, the page immediate comes up right with a white background, and black text. Before the page finishes though, the background turns to light blue, and the text turn gray. The logos show up right framed in the white background but the rest of the page is light blue. It happens in other websites as well. There backgrounds are right, but where the text is located is like in forums the text is grayed out, and there background colors are faded too.
