Brandt, I don't think anyone uses 9000K lighting. It would take a lot of CTB to get lights up to 9000K. I think you need to balance to the sun itself for most shots. Stick with 5600K and gel slightly to suit your tastes. That golden look at sunset is caused by the sun itself appearing a lower color temperature than the blue sky above. The greater amount of earth's atmosphere that the sunlight must pass at sunset filters out some of the blue.

If you want to fake sunset, fill with 5600K and gel down a light coming in from the side to a lower temperature using CTO or CTStraw for a more yellow sun. I got a nice effect once by adding some 1/4 minusgreen (magenta) which made skintones a bit richer. I was shooting with an actress with very tan skin, so I don't know if this would be flattering to a person with more pink skin.

I guess the real answer is to start with 5600K and test different settings/gels until it looks like you want. If the sun moves low in the sky during your shoot, adjust to a lower temperature with gels. White balance whenever the scene or the lighting changes.

Thanks for the tips, Marcus. I'll start testing.
