Yay, and thank YOU!!
Edit: I went over and looked. So the point of dark mode is to make things easy on the eyes, and to reduce interference with melatonin production. Melatonin production is blocked by blue and white (because it contains blue) light. The best option for dark mode is black background and orange type, as it provides good contrast with minimal interference with melatonin production.
The classic example is the White / Blue of Facebook - designed, no doubt to keep users awake, and clicking. I noticed sometime ago, that screen invert in iOS yields, White --> Black, and Blue --> Orange. Technically speaking any light will reduce melatonin production to some degree, some researchers would say, even being able to see your hand in front of your face, like at all, will do it. And the biggest effect is from Blue and White light. :-)
