I've made some brightskins for Painkiller (Booh version coming soon). Colors are based on Quake 4 game. The new textures aren't affected by shadows so more brighter even in the dark because they use _add texture. You can choose between 2 items version (colored and not colored).
Ammo Shell, Ammo Freezer, Ammo Stake, Ammo Rocket, Ammo Shuriken, Ammo Electro, Megapack.
