For just a slight bluish tint and the best light output, I woild suggest 9005's either Hyper or Eurolites. I really liked the 9006 Eurolites I had. I used 9..6 Hypers for awhile but were more white sometimes, did the high to low beam mod with the Hyper 9005's and light output was very good for a blue bulb and a nice color blue.
Right now I'm running 9006 Cuzos and I really love the look, but might be a little too blue for you.
