Interesting observation, something I haven't tried.
If I want to watch my newts after dark I use a red torch (bicycle rear light!). It's something I've always done to watch nocturnal catfish as red is apparently invisible to them, I think the newts can pick it up better than the fish, but they don't seem bothered by it and carry on as if I wasn't there.
