Why are some shapes pink and others black?

Software Carbide Create
#1

I’ve imported my design into Create, and noticed that the outer profile shape is displayed in pink, while my lettering is black.

When I go to create Toolpaths, I’m able to easily do so with the letters. When I choose a pink line, however, it says ‘empty toolpaths’. Any help?

Magenta indicates unclosed/open paths which are limited in what paths may be assigned.

Ah gotcha. I’ll need to go back in then and fix it.
