Why don't you add it to all your pages?
I don't think changing colors makes
pages like this any better.
You could just load the same css file to all pages, they would look all alike.
I have 30 million files on this server. Not all of them are HTML, maybe "only" 20 million, but adding a few kB to each of them quickly adds up to tens of GB extra (in terms of storage and bandwidth).
maybe you can do it in your server settings, like .htaccess or similar without even touched each page code.
I wouldn't know how, but if this is possible, it may work for some sections.
