Thank you Aslain. I made changes and this is what I wanted. (see picture)
But now ally and enemy damage texts has no shadow so I will try to keep them while protecting new color. If anyone wonder I used 0xFFC71C
EDIT
I found easier way than what Aslain suggested. Open only colors.xc file and change the following parameters to whichever color you want:
"pl": "0x775A00",
"player_ally_blowup": "0x775A00",
"player_ally_hit": "0x775A00",
"player_ally_kill": "0x775A00",
"player_allytk_blowup": "0x775A00",
"player_allytk_hit": "0x775A00",
"player_allytk_kill": "0x775A00",
"player_enemy_blowup": "0x775A00",
"player_enemy_hit": "0x775A00",
"player_enemy_kill": "0x775A00",
"player_enemytk_blowup": "0x775A00",
"player_enemytk_hit": "0x775A00",
"player_enemytk_kill": "0x775A00",
"player_squadman_blowup": "0x775A00",
"player_squadman_hit": "0x775A00",
"player_squadman_kill": "0x775A00",
The result is on the pictures.
