Base the coloring on a color scheme. Maybe user selectable?

@Urtgard
Just need to ask, as it might be me misunderstanding.
Ref. your video:
Will we no longer be able to mark a pull, and add mobs directly into it? As such, will we have to merge pulls in the list instead?

If so, it might cause too much extra work for the user when editing MDT runs.

The color options though looks perfect 👍

You mean like this?

Yes, like that. Good :)
I guess you used shift-clicking in the first video. I completely forgot about that keybind.

How do you get it to color automatically? I'm doing shift+click and it makes new pulls but not coloring anything automatically. I don't have a "colors" button to enable these options. I'm using v3.0.2

implemented in #141

Suggestion for color scheme:

Alternating between warm and cold color gradients.
To give clear indicator as to what NPC's goes into each pull, when looking at the map.

Example (first 10, but ofcourse go through the entire wheel and starting at "1" again):
