stefanno yeah it's pretty tough to make the colors of the video and pass-through feed match well. Especially at night.
I bought a 100w floodlight that makes the passthrough as good as it can get at any time but I doubt many are willing to do the same. Besides it will still need quite a bit of color correction then. Like what I do is up the overal warmness (night filter) and decrease the brightness on my quest then increase brightness and contrast of the video to make everything seem normal again and aligned, sometimes the only way to get close to the color is by using the color profiles too).
Not exactly plug and play to get the best experience yet color wise. But that is also a large part due to the passthrough quality of the quest at low light. Still DEO could probably improve this by making it easier to match those colors somehow. A simple thing would be to have persistent video settings for colors etc. But what would really be cool is to have something like an auto match function/ calibrate color. You can't access the feed of the passthrough as a dev in quest but you could probably overlay a color correcting filter/ multiplier on the background. Something like that.
