The LESS blue the light, the BETTER the output. Keep that in mind. Also, don't install HIDs into your high beams. Not worth it, as they take too long to warm up, and you'll turn them on and off enough times to kill the burners in 3 months...
Just use GOOD CLEAR halogens for the highs with a relay harness for the highs, and wire the lows to stay on with the highs. Can't get any better than that...
