I know programmers are prone to legal hacks that don't make sense, but I'm curious whether the following would work.

As I understand it, it's ok to reference a Pantone Color by name without a license (nominative fair use), but that gives you no idea how to use or display it. So photoshop files could store both the pantone color name (for printing and profressional color matching purposes) and a substitute color for display on screen when unlicensed.

The UI would either prompt users for the substitute color, or automatically fill it if they did have a license at the time they selected the color. That way files wouldn't break quite so horribly when licenses expire.
