Where are healthbar colors defined?

[Frotron9000]

@ExXHaloMasterX By the use of incredibly sophisticated analytical analysis of the game data (screenshots + searching for RGB values in game data) I was able to find the corresponding file. The colors are all stored in the file resources\_common\drs\interface\50500.bina, which is just another palette file. The colors for each player are distributed as such:

P1: Line 24
P2: Line 40
P3: Line 245
P4: Line 247
P5: Line 255
P6: Line 256
P7: Line 17
P8: Line 89

Edit: It appears though this file can not be modded?
See my other thread here:

File can not be modded

I am trying to mod the file resources\_common\drs\interface\50500.bina but it appears the file is not overwritten when I place it in this folder in my mod. Is there a certain limitation to which files can be modded?
