...and if you don't want black outlines around color outlines, just work on the original outline layer or duplicate it for safety. Make sure they're not antialiased then, though. A good habit is to scan your lineart in high resolution and then set it to monochromatic image mode for a moment, or if you draw the lineart with tablet, use the pencil tool. You can shrink the finished image to add antialias and make it web friendly, plus you also have a high definition image for pritinting, too.
