How would I change a Weapon's Material?

[Smileytopin]

I want to add custom colored weapons on to my server, like a red deagle or a Ak-47 that looks gold, how would I manage to do that, without adding new models.

This code is what I am trying to do to make the m16 gold, but ents.SetMaterial isn't working ;/
if CLIENT then

SWEP.PrintName = "M16"
SWEP.Slot = 2

SWEP.Icon = "VGUI/ttt/icon_m16"
end

SWEP.Base = "weapon_tttbase"
SWEP.Spawnable = true
SWEP.AdminSpawnable = true

SWEP.Kind = WEAPON_HEAVY
SWEP.WeaponID = AMMO_M16

SWEP.Primary.Delay = 0.19
SWEP.Primary.Recoil = 1.6
SWEP.Primary.Automatic = true
SWEP.Primary.Ammo = "Pistol"
SWEP.Primary.Damage = 23
SWEP.Primary.Cone = 0.018
SWEP.Primary.ClipSize = 20
SWEP.Primary.ClipMax = 60
SWEP.Primary.DefaultClip = 20
SWEP.AutoSpawnable = false
SWEP.AmmoEnt = "item_ammo_pistol_ttt"

SWEP.UseHands = true
SWEP.ViewModelFlip = false
SWEP.ViewModelFOV = 64
SWEP.ViewModel = "models/weapons/cstrike/c_rif_m4a1.mdl"
SWEP.WorldModel = "models/weapons/w_rif_m4a1.mdl"

ents:SetMaterial('cs_italy/yellow')

SWEP.Primary.Sound = Sound( "Weapon_M4A1.Single" )

SWEP.IronSightsPos = Vector(-7.58, -9.2, 0.55)
SWEP.IronSightsAng = Vector(2.599, -1.3, -3.6)

function SWEP:SetZoom(state)
if CLIENT then return end
if not (IsValid(self.Owner) and self.Owner:IsPlayer()) then return end
if state then
self.Owner:SetFOV(35, 0.5)
else
self.Owner:SetFOV(0, 0.2)
end
end

-- Add some zoom to ironsights for this gun
function SWEP:SecondaryAttack()
if not self.IronSightsPos then return end
if self.Weapon:GetNextSecondaryFire() > CurTime() then return end

bIronsights = not self:GetIronsights()

self:SetIronsights( bIronsights )

if SERVER then
self:SetZoom(bIronsights)
end

self.Weapon:SetNextSecondaryFire(CurTime() + 0.3)
end

function SWEP:PreDrop()
self:SetZoom(false)
self:SetIronsights(false)
return self.BaseClass.PreDrop(self)
end

function SWEP:Reload()
self.Weapon:DefaultReload( ACT_VM_RELOAD );
self:SetIronsights( false )
self:SetZoom(false)
end

function SWEP:Holster()
self:SetIronsights(false)
self:SetZoom(false)
return true
end

Please use code/lua tags to wrap code.

Secondly you can call weapon:SetMaterial( ) to reset the material, and for example a nice looking material is Phoenix Storms Chrome as demonstrated below.

weapon:SetMaterial( "phoenix_storms/chrome.vtf" );

Sorry about that, and thanks for the reply!
