This is probably a simple answer for most people, but I can't figure it out. My problem is that the path that I make with my pen is yellow instead of black, so I can't see my bezier handles on the white background. How do I turn it back to black? It happened after I opened an AI CS2 file in CS3, then changed all the type to outlines. Each block of type had a different color for the outlines ending with yellow, and now everything that I make has that yellow (nearly invisible) outline.
With the object selected...
If you need to change the stroke color, double-click on the Stroke tool on the tools palette - near the bottom. (probably not what you meant : )
If you want to change the highlight color of the path (including the handles), highlight the layer in the Layers palette and click the Layers palette "triangle" drop-down menu and choose "Options for Layer XX", there you can change the color to whatever.
