How to change the color of radio command

[pineappleplay]

I need help in changing the ttt_radio commands a different color

so if someone calls ttt_radio innocent the chat would be green and if someone call ttt_radio traitor it would be red.
i really need help with this

/gamemode/terrortown/gamemode/cl_voice.lua

local function RadioMsgRecv()
   local sender = net.ReadEntity()
   local msg    = net.ReadString()
   local param  = net.ReadString()

   if not (IsValid(sender) and sender:IsPlayer()) then return end

   GAMEMODE:PlayerSentRadioCommand(sender, msg, param)

   -- if param is a language string, translate it
   -- else it's a nickname
   local lang_param = LANG.GetNameParam(param)
   if lang_param then
      if lang_param == "quick_corpse_id" then
         -- special case where nested translation is needed
         param = GetPTranslation(lang_param, {player = net.ReadString()})
      else
         param = GetTranslation(lang_param)
      end
   end

   local text = GetPTranslation(msg, {player = param})

   -- don't want to capitalize nicks, but everything else is fair game
   if lang_param then
      text = util.Capitalize(text)
   end

   if sender:IsDetective() then
      AddDetectiveText(sender, text)
   else
      chat.AddText(sender,
                   COLOR_WHITE,
                   ": " .. text)
   end
end
net.Receive("TTT_RadioMsg", RadioMsgRecv)

i believe that this is the function i have to edit
