[otrs] Change the color of "NOTE" in Ticket

Hello, When agent closes the ticket, it is in red color and when one write the note, its also in "red" color. So, its confusing. I would like to change the color of NOTE. (I have enable Sysconfig setting: Ticket::UseArticleColors ) Any idea? Is it possible in OTRS 4.2 ?? Is there any development going on to create new article type? Thanks in advanced for your time and input. Cheers,
