On the GT, the single low beam is also on with the two high beams. There is a definite difference in color between the 6000K HID lamp and the (my guesstimate) 3,800K halogen high beam lamp. It's orange over blue on my garage wall.
Damn that curiosity of mine....
Made me find my old Gossen photography color temperature meter. Low beam HID reads 6,800K. High beams -both - (halogen) measure 3,200K. Never thought they were that "orange" but they are. I'd guess the lower voltage of the stock halogens would fluctuate in color far more than the 23K volts supplied to the HID xenon lamp.
Some people can see better in the yellow/reddish spectrum light than bluish, so say the neon sign makers who use red neon over blue mercury-argon signs. Red neon just seems to punch through fog and rain better, sort of like a low-tone fog-horn over high. How much better you can see in high-Kelvin bluish lights is very subjective in nature. Some orange high-pressure sodium lamps just seem a bit weak to me for any sort of distance vision, but they are wattage savers. Conversely, a very blue 12,000 Kelvin HID lamp seems almost invisible to me shining down the road at any wattage.
Damn, I'm seeing lots of dots before my eyes now......
