Here is something I don't understand :
on your daylight control group, your WB is 5400 and your RGB components are something like R70, G71, B75. A look at the color meter recording shows a slight bump in the blues and a gap toward the purples.
on the tungsten light, the color meter recording show a nice slope from the purples to the reds. RGB values for the white are something like 71, 72, 73. You explain that the blue is boosted to compensate the weak blue in the spectrum and the red diminished to compensate the strong reds in the spectrum (to attain balance).
How come then that in the daylight example, the blue value is much stronger than red and green while the blues in the spectrum are as high or higher than the rest of the spectrum ? Shouldn't it be the opposite ?
