Anyway, as far as I understand the question, there's no fundamental difference; it's just a matter of personal preference.
And if you look at it from a global perspective, let's say you don't want the color to change for just one dwelling, but for 10 dwellings. Instead of setting a condition in each dwelling that triggers a player change, you can use a trigger event. You place this trigger event in each dwelling, and then enter the conditions for this event only once, for example, in calendar events.
