Hi lubenko,
the colors are fine, I don’t want to mess with those! 
What I meant is that you have to set the maximum and minimum values yourself, without knowing what the real range is.
That means in my case that many connections are blue and only a few pink - so that means a lot of the color range is wasted.
I guess what I would like is that the inspection tool determines max and min count by itself within the group of selected cameras and distributes the colours within this range.
I know the mathces feature already. What I mant though is that you select one camera and it shows you only the connected ones like in the inspection tools…
