They make 194s in blue (lights under the dash). I don't remember off the top of my head what the reading lights are.
You can also get sheets of theatrical/lighting gel and get a similar affect from what I hear.
this is an old post, one of my firsts, that discusses the idea of interior lighting a bit,
This was back when Jim W was driving his Bonneville "Red Light District" and thats how he made the interior lights red, so you might PM him or some of the other members who chimed in there.
