Ok im less pissed now... anyway the there are three main color settings which can be achived by setting a units hp to 1/3, 2/3, or 3/3. Dispite hwat you may have herd from people like XGuy( idk if he posts here) 3/3 is not 3 hp. Like i said, its also dependant on tileset.
Badlands/jungle: Glows blue, darker blue, and brown.
Ash: Glows orange, shades or red(i think, it might just be another shade of orange), and brown
Twilight: Dark blue , darker blue, brown.
Space/Installation: Dosent glow, but it has this weird neon blue efect.
Desert:Cant remember.
Arc: cant remember eather, but i thnk its just brown and two shades of blue. probabaly lighter than badlands and definately lighter than twi.
Note: The brown in all of these dosent glow... ever. Oh, and 3/3 dosent show some of the colors, its mostly black. Theres more but sts is playing in the background and its pissing me off evev further.

EDIT: Dseert is just shades of brown. Two of which glow, one dosent.
EDIT: FYI, other hp values work, i just like to use thoes 3.
EDIT: Ice or Arctic or w/e is what i thought it was.
Note: Its a good idea to eather make the units invinsable or set their hp over 9999 when your using this. Having 4/3 hp just looks unprofesional.
EDIT: Units that have their shealds set to 10000(or anything over 9999) that usaly dont have shealds wont have shealds at all, but you still cant see their hp. I find this extreamly useful.
EDIT: Again, like i said, you shouldent use terran units or most protoss units b/c of their wireframe thingys. Some times they work, other times they just turn orange, green, yallow, etc. Ill post a list of units that work.
EDIT:
-All zerg units(not sure about buildings)
-Archons and Dark Archons
-Recorce nodes(mineral thingys type 1 2 and 3, geysers)
-Mineral chunks (type 1 and 2), Gass sack things(1&2), and the gass tanks(1&2)
-I cant remember but i think that big ass crystal formation thing works too.
EDIT: Im getting tired of editing, ill finish when you people post something.
EDIT: Does anyone else think its just alittle creepy that this topic has been here for 2 days and it had over 100 views? And no, im not adding anything else even remotely relavent till someone posts.
EDIT:

nvm, my freind dosent want me to.
