Kill Icon help

I just made a bunch of kill icons that I want to use with one of the weapon packs, which didn’t have kill icons initally. When I kill something with them it still says: Warning: killicon not found ‘akgp_weapon’.
Related to this


local Color_Icon = Color( 255, 255, 255, 255 ) 
killicon.Add( "akgp_weapon", "HUD/killicons/akgp", Color_Icon )

The killicon does exist as a vmt and vtf in the directory I point to.
What do I need to do?
How do I make my icon replace the default one, is there a hook i need to use?

Ok, I have my icons working now but they will only show up in white regardless on the color value I use. Any thing that might be causing it? The icons are white in the vtf.

How did you get it to work?
