Is there a way to tint an entire web page a certain colour? As in, not actually altering the images and other content to be tinted that colour, just for the content to look that way when viewed on that page. It sounds to me like something that could be done with CSS but I'm really not sure. Google's results aren't turning up quite what I'm looking for, although maybe I just suck at finding the right words for this query.
