Ok, so I made an entire design in illustrator, with a bunch of layers and whatnot. Currently, it is on a white background, however I want to put it on a Navy Blue one. Great, so I figured I would just add a navy blue layer underneath all my other layers...however, when I do this, the white part inside my text becomes navy blue. How do I set my text to no longer be transparent, and to just be white text with black outline? Thanks!
