Simple enough?!?! lol jk
OK, I forgot... You're young enough that you don't NEED extra fiber in your diet. Some of us older farts take daily supplements...

I know the results of mismatched color temperature settings very well, thank you. My point was that there is no such thing as "normal" lighting conditions, it's a meaningless term.

If I'm shooting in the studio under quartz hot lights, I'm dealing with a 3200ēK color temperature light source - a very "normal" situation. Shooting in the studio with flash, I know I have a constant 5500ēK light source, again , quite "normal". Shooting out of doors, using the light of the sun, is the LEAST consistant color temperature model I can think of. Just because you're outside doesn't mean you're getting 5500ēK light. The atmosphere itself, sky conditions (clear, partly cloudy, full overcast), angle of the sun relative to the horizon, and whether or not your subject is illuminated by direct sunlight, or in partial shade, in full shade illuminated by a blue sky, can throw the color temperature readings all over the map. This is why pros own and USE color temperature meters! We don't rely solely on the LCD screen on the back of the camera, a dial on the top of the camera with icons, nor do we completely trust in Dr. Land (Polaroids) when it comes to getting accurate color.

Try this: On a clear day with a nice, deep blue sky, set your camera's white balance to 5500ēK (a.k.a. "daylight"), and photograph someone in a shady area where the only light falling on them comes from blue sky - no direct sunlight. Odds are, the color temperature of the light on your subject will be about 20000ēK (a DM value of 5). Since 5500ēK has a DM value of 18, the filter to correct would be R13. The closest filter value without going over the DM value is R12 - the EXACT opposite of the B12, which is the filter you would use to get the same result you originally described. You can also get the same effect by shooting in RAW (with the correct white balance setting on the camera), and selecting a different white balance setting in your RAW converter.
