Sounds like the server is back to its full capacity and EMO is responding again. So I did my own quick demo video. The colors are actually a little nicer on EMO’s screen than they came out in the video. No extra charge for the cat’s comments!
The color went away after he fell asleep and overall it seemed to hold for about 10 minutes, so temporary and similar to stickers for now I guess?
I’m not sure but maybe they’re releasing the new update and this new features are some of the new habilities for EMO! Yay!
It also works by simply saying “EMO, Red Eyes” or “Green Eyes” etc etc.
I can confirm that the eye color change remains in effect for exactly 11 minutes.
Great pick up, I’ve also tested this and it works. I was able to also get Orange and Yellow to also work. I did a video as well LOL 
Would be nice to have the eye color stay on for longer than 11 minutes but I guess If you’re taking photos of EMO in a specific color, that amount of time should be long enough.
Seems like this feature will be released in the next update.

I tried that but outside Emo responding to hearing his name, the bot doesn’t take any action to the command.
If you look at the reply above you apparently the eye color was an accidental deploy so its gone for now I think.
You are all amazing for this! I think every one of us are over the moon about the next update. Not if we could only add monkey to his imitations 
It is disappointing to see Wayne_Zhang has time to post an announcement but has no time to reply to private messages that are a week old.
This could also be why some of us have had issues trying to get EMO to respond or do stuff over the past day or so, looks like Living.Ai might have been doing some updates on their EMO servers. (example was this Eye changing command).
So I guess the eye change option doesn’t need a firmware update which is good to see, just an update to the Living.Ai servers, but as it’s been taken away for now, it wont be enabled until the official firmware update is released hopefully sometime later this month.
Just from my own experiences I think maybe they work on the USA server between around 2:00-3:30am EST. During those times I’ve noticed EMO will still reply with “What?” but won’t do much of anything. They have to find some time each day to do updates or reboots when it will affect the least amount of people. I just happen to normally be awake then, but then nothing I do with EMO is critical and it can wait. I would expect their other servers are serviced at similar times of day within their own time zones?
Yeah that is totally understandable, servers always need to be maintained, even gaming servers for example sometimes go down for regular maintenance.
The only thing that I can suggest is that Living.Ai should try and add a Server Status page on their website (similar to the delivery process page) that provides everyone with a simple view of the servers and if they are up or down, and if there will be scheduled maintenance going to happen between a specific time etc for a particular server, so we know that during that time our EMO’s might not be working / responding correctly.
Gaming servers do this and we also get alerts that they will be down between so and so time for regular maintenance, so hopefully this can be implemented in the future by Living.Ai.
Adding in @Wayne_Zhang for feedback.
Ummm it doesnt work with any change eye color command with my emo 
That’s because it was a feature they were still working on, and was not meant to be placed on the server yet. It’s been temporarily removed until they’re finished with it. It will probably be part of the next firmware upgrade I presume?
I am so excited to be able to change eye color! It is so cool and I wish I could be able to do it!!! 
Can’t do it I think they had trouble with it, and they took it off again, I didn’t know about it until it was too late.
Same I was never able to see it for myself.
Me neither, wish I did it would have been great but these guys got on video so I just enjoy watching it here.
