Modify the selection area color; default is ffffff which is white. When you make a selection, that area becomes an inverse image which by default becomes a whitish color. You can set it to a different color by modifying the hex value in the box next to Highlight inversion color. Keep in mind that if you set the value to a low value, you will not be able to see the outlined selected area (for example the hex value "f" is not readily visible and leads to confusion). A leading 0 or blank is not allowed and will be automatically changed to ffffff.

You can choose the background color of the viewer window.
Composer BG Color
Default is BT601; others BT709 (high definition), BT2020 (ultra high definition). PAL and NTSC have different color primaries, so
BT601 = SMPTE 170M = BT 601_525 and
BT601 = BT 470 BG = BT 601_625. BT 2020 can be
BT2020 (non-constant luminance) or
BT2020 (constant luminance). NCL is the standard.
