I looked at the DahuaWiki page and understand what it does, but which sensitivity setting forces it to stay in color mode with less light, low or high?
 
There is also a time setting, which I set to 2sec. I'm trying to get my front door starlight cam to stop changing to b/w occasionally in the morning when the porch lights go out. Seems to be right on the edge.
