White balance is a red-blue adjustment of the image. To adjust the
green-magenta balance, use the color compensating (CC) adjustment.
For example, a fluorescent source will have peaks in its spectrum that
cannot be corrected with the traditional white balance. The CC shift can
correct these peaks up to a full green or full magenta gel. One step of
CC SHIFT is equal to 035 Kodak CC values or 1/8 Rosco values.

ARRI recommends adjusting white balance and color compensation
using appropriate measuring equipment such as a vectorscope with
calibrated gray card or a color meter.
If the desired white balance setting does not appear in the WHITE
BALANCE list, a user-defined white balance can be added.
To add a white balance:
1. On the HOME screen, press the WB button.
2. Press the ADD button.
3. Rotate the jogwheel to adjust the white balance value in steps of
100K or press the + 1000K and – 1000K buttons.
4. Press the jogwheel or <> button to select the CC adjustment.
5. Rotate the jogwheel to adjust the CC value.
6. Press the jogwheel to add the new white balance to the WHITE
BALANCE list.
To perform an automatic white balance:
1. On the HOME screen, press the WB button.
2. Press the AUTO WB button.
3. Place a well-lit gray card in the center of the image and press the
AUTO WB button. The ALEXA will calculate the white balance and
color compensation values and set these values for the "Auto WB"
entry in the list.
Note: The automatic white balance will be overwritten each time a new
one is calculated.
