The 'Color Control' tool ('Hardware' tab, right panel) allows to change white balance of the cameras. The panel conditionally can be divided into two sections: presets list (on left) and presets control buttons (on right). Switch between presets by clicking on the list items.
To create new preset, follow the steps:
To delete a white balance preset, select it and press the 'Delete Preset' (with icon minus) button.
To rename a preset, double click on it in the list with the left mouse button.
White balance presets are saved between DM launches.
