The HID color temperature I chose was 4300K. A bright white color, similar to daylight. 5000K and up would look blue or violet. Halogen lights have a color temperature of about 3000K and are noticeably yellower.
Here are photos taken from about the 90-foot mark, approximately four feet from ground level. Again, I kept the camera settings the same (at F3.5 and 1/60) for both shots.
