Different color Guides via Rulers

In laying out a site, it’s very useful to use Guides via the horizontal and vertical rulers. However, on my site there are many pages (it’s a literary magazine), and it would be very useful to be able to make Guides different colors (or even attach a visible name to them) so on each page I know where to snap different elements. Having all Guides blue is confusing when moving text boxes or graphical elements around if you’re trying to adhere to a specific styles on groups of pages. Thanks!
