Good undead vs Evil undead: Watch their color.

Hi all. I wanted to talk about a detail i've notice that separates good undead and death based champion from evil ones that have ties to the shadow isles. and that is good undead/death based champions like and have a blue hue while have a sickly green glow/hue or if they are (Proto)noxian have no glow but red eyes instead like ( and are exceptions, Karthus's steely-blue hue could be due to him being misguided, while Evelynn as usual, is a mystery.)

So it could be possible that any death based champion that are good by nature have a blue hue to signify that they are noble while the others are not. Food for thought.
