DarkRP Printers - Changing color.

Hello, i’m in the process of making a money printer that you can add an ink entity too.
I am using NWInt
Currently i’m trying to make it so if the printer runs out of ink it turns red.
In function ENT:Think i have put

	if self:GetNWInt("ink") < 1 then self:SetColor(255, 10, 10) end
	if self:GetNWInt("ink") >= 1 then self:SetColor(0, 0, 0) end

but… the printer does not change to color(0, 0,0) when i put the ink in… Can anybody help me out? Thanks in advance.

you need to put self:SetColor( Color( r, g, b, a ) );
