Differentiate the archives folders by putting them in red, in ital
 

First of all for my bad english.

In my work, I often this claim which is regularly:
"There I often confuse archives folders and those of my mailbox since they
have the same name".

I would like to differentiate the archives folders by putting them in
italics or red for example.

Have you an idea to resolve this "problem"?

Thanks in advance
