How to maintain unit model color and transparency under various effects?

[WC3Wonderer]

Hi. I want to change color + transparency of the unit to reflect the state of my custom ability but I found that if I cast invisibility or windwalk then after these spells expires transparency will be reverted to original value, not the one that I set in the script.

However If I change 1.color+transparency then 2.add ghost ability (modifies color and transparency) then 3.remove ghost; the engine will return color of the unit to values I set in step 1.

1. How to keep color + transparency like the engine do it with the ghost?
2. How many abilities (besides invisibility and windwalk) can change model color/transparency in the vanilla game?

I dont know for 1, but Banish, and perhaps Cold Effect (Frost Nova, Cold Arrow) can affect that.

Envenomed Spears or Slow Poison or something else similar gives a green unit tint, doesn’t it? (Or did WoW rot my brain?)

The visual dot thing is green bubbles but the unit keeps the same color, I diagnose you with a severe case of WoWite
