What is the "Object Color Rules" addon?

I was looking through the addons list and noticed this addon.

I don’t know what it does. I tried messing around with it but nothing happened. I also cannot find any information about it online. The documentation it links to is marked as “to do”.


This is for defining some rules (and give them colors ??) with some text to select and what type to selcet from (no text → select all)… see Campbell Barton’s answer:

I’m not sure what the color and opacity does mean … (maybe different ly used in 2.79 ??)
