Here's a boring 8 minute video that demonstrates a bug with the Color Range function of Adobe Photoshop beginning with the first version of Creative Cloud and how to avoid it.

This problem results in inverted, solid and void channels when running an automated process such as a color separation. The fix is very simple.
