This seems like such a silly question, but I have gone through as much of the ISY documentation as I could and didn't find the answer.

In the ISY994i Admin tree view, some of the nodes are shown in blue and some in pink (see attachment). What do the two colors represent? Some of the ISY Wiki pages show these two colors but never explain them.

The same as for scenes. Red is for controllers only. Blue is for responders/controllers.

Your sensor can only be a controller which is why it's red.

Hmm - now I am confused more. I have sensors (such as the Zooz ZSE42 leak sensor) display in blue, and switches (which can be both) in red.

Your switch may be an actual scene controller (not all zwave devices are scene controllers). 

Yes, the switches are all capable of being scene controllers. Some are in blue (that LR Controller, for example) and some are in red.

I think Red is supposed to be for controllers and blue is supposed to be for responders, at least in scenes (source: ISY-994i Home Automation Cookbook). However, I've seen this question asked a lot over the last 10 years  and have never come away with a clear understanding of the differentiation of the colors in the node hierarchy.

I've also wondered about this... I couldn't find out why there were color differences.

Also in a couple of places in the cookbook

Hopefully the upcoming ZMatter firmware upgrade will get ZWave scenes working as outlined some time ago.

Are you certain? There can be different firmwares for exactly the same product (heres looking at you fibaro, dome, ge, Eaton, and a couple more). In the zwave world, there is a difference between an actual zwave scene capable controller and a device that can control another device via the isy. If everything is exactly the same then I dont have an answer for you.

It's possible I do not understand the term fully. The switches are the Zooz ZEN71 and ZEN34. The documentation shows them capable of initiating scenes, but you're right that they rely on a hub to respond to the request.

As @lilyoyo1pointed out, there are different options for each Zwave manufacturer.  I also believe that the current ISY firmware is not very Zwave Scene friendly, but apparenly that is about to change.
