Projectile color

[SpecT]

Hello folks,

I was wondering how I could set color to the projectiles that are being shot from hunter (for example). I think it's gonna happen by using shaders but I'm not really sure so I want to get an answer from people who know about it.
I would appreciate it to know the trick.

Thanks in advance!
