well...i was map-making as usual on my computer one day experimenting new types of health for my Bounder units and well i had this 6/2 health on a bound i made before in badlands i said well let's put the same black health effect on this bound and the tileset was platform and WHOA!
the health became blue! i said holy sh...me pro! woo hoo
then i got more involved to get you not bored
my conclusions after 1.34 hours of testing were:
1) you can only 3 diferent types of glowing health this is for all zerg units, archon,
beacons,critters and resources
2) the health for terrans* and protoss is random it has no stability as the other ones i mentioned
3)health depends on the tileset you have EX. in badlands-jungle health will go black in ashlands it will go orange/red and in space it will go blue and stay just blue
*terrans health doesn't changes according to the tileset
the other day(today) i was experimenting with players and sprites all that stuf
and WHOA! <conclusions>
1) as the health the player that are not normal change their color
2) i mean p156 for EX. will have blue dots and stay blue in badlands will go black and stay and my favourite in ashlands it will go orange /red black (animated

)
well that's all i have right now i g2g so i will post pics very soon and i will get you work experimenting new things with this i told you
