I have found something in 
resinfo\ifchatviewer.txt.
Code:
   GDR_STATIC_ALLYLAMP:CIFStatic
   {
      ClientRect=RECT,"0,0,0,0"
      Color=COLOR,"255,219,194,70"

      Text=STRING,""

      UV_RB=POINT,"1,1"
      UV_RT=POINT,"1,0"

   GDR_STATIC_ALLLAMP:CIFStatic
   {
      ClientRect=RECT,"0,0,0,0"
      Color=COLOR,"255,126,135,120"
      DDJ=STRING,"interface\\chattingwnd\\chat_lamp_all.ddj"

Notice the 
Color=COLOR,"255,201,197,231" and 
FontColor=COLOR,"255,255,255,255"?
Edit: Turns out this is for the little buttons above your chatbox.
