Putting out a CSS file through PHP will add overhead to the server as you will have dynamic HTML and CSS to create. Given the 'cascading' nature of CSS, any inline style served in the HTML pages will override the CSS, so it's quite likely that you can simply add some inline styles into the pages already being served by PHP. Another option is to update the CSS using Javascript, here is one way to do this, but I don't believe this works in all browsers (I use this in Webkit on iOS):-

var cssStyle = getCSSRule('#styleName');
cssStyle.style.background = redfinedColour;
