I have Multi-state indicators setup…

0=Green  
1=Red

But I’m also needing to change color for bad tag quality, say gray. How do I make this happen? I keep poking around and I’ve been unsuccessful. A bad/offline tag will not have a value so I can’t figure this out.

You can use the quality property of the tag, or more simply, the [isGood](https://docs.inductiveautomation.com/display/DOC80/isGood) expression function

Any good write-ups for this? I haven’t been able to find any. I think I’m close but it’s not quite working now I need it to.

If you want to be explicit, you can use [`binEnc`](https://docs.inductiveautomation.com/display/DOC80/binEnc) - `binEnc(isGood({tag}), {tag})`. It’ll return an integer value that’s the binary complement of the booleans provided; so your truth table becomes:

| Quality | Tag | Binary | Integer |
| --- | --- | --- | --- |
| bad (0) | 0 | 00 | 0 |
| bad (0) | 1 | 01 | 1 |
| good (1) | 0 | 10 | 2 |
| good (1) | 1 | 11 | 3 |

Then you can explicitly specify the rendering in the style customizer for any of the possible states.
