[Metallica_Band]

Hey there...I am a big "fan" of using guides...both in Photoshop and Illustrator...guides can be a great big help when you want perfection...well I have a bunch of guides in Illustrator...I use them to point out where specific points are located...so I can "snap" other points right on top of another point...well all the guides are one color...

I was wondering if there was a plugin to give them diferent colors or something that will make them (or a grouop of them) unique...get what I'm saying???

THANX
