But the color change for hero or team mates or enemies must be added / implemented. I really really keep loosing my hero in the middle of the rompus. It should be customizable also, some are color blind to some colors.

Colors are a great idea but i don't think its the way to solve this issue. In dota even with the colors it never helped me locate myself or see myself better on screen. it only helped me to pick out which enemy was were. I also believe it promotes bashing. Char names like Yellowisafag or Purplesucks or blueballhost to name a few. The ping system works way better to pic out a target and the space bar is so amazing at re-centering your view colors are probably not needed. I was never one to scan the map and constantly look at what others are doing. i can now and still dodge spells and the junk.

I think an aura at the feel of the hero in some arbitrary (customizable?) color would at least would be pretty helpful. Having played dota for a loooonnnggg time - i dont often lose track of my hero (exceptions like aoe buttsuripise duly noted) but it is a cool idea.

Or better yet, just keep things the same, TEAL and RED, however my hero should have a different color overall, something like GREEN or PURPLE ... or mmmm.. YELLOW! An outlined 'aura' around my character would also certainly help.
