How can I make Quake3 look more like Quake1/2 with regard to colour

This is a common complaint from players who have moved from Quake1 or Quake2 to Quake3. First I strongly suggest that you try to get used to the new, brighter colours. If you cannot then try the following settings

seta r_overBrightBits "0"
seta r_intensity "1.125"
seta r_vertexLight "0"
seta r_mapOverBrightBits "2"
seta r_gamma "2" // This needs to be higher than your usual setting, alter as needed

After you have made those changes issue a vid_restart command at the console.
