I'm with you, Steve. I think it does start to look unnatural. My preference is to have the same color temperature for all the uplighting and a cooler color for the moonlighting (like 2700 - 2900 for up and 4000 - 5000 for down). I realize that colored lenses can make certain colors "pop" more but it isn't my preference.
I also can't imagine what a hassle it would be to change color filters or lamps on all of my jobs every 3 months to match the season...
