 \paragraph{Highlighting Inversion color} \index{inverted colors} Modify the selection area color; default is \textit{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 \textit{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 \textit{ffffff}.
 \paragraph{Composer BG Color} \index{background color} You can choose the background color of the viewer window.
-\paragraph{YUV color space} \index{yuv color space} Default is \textit{BT601}; others \textit{BT709} (high definition), \textit{BT2020} (ultra high definition).
+\paragraph{YUV color space} \index{yuv color space} Default is \textit{BT601}; others \textit{BT709} (high definition), \textit{BT2020} (ultra high definition). PAL and NTSC have different color primaries, so $BT 601\_NTSC$ = SMPTE 170M = BT 601\_525 and $BT 601\_PAL$ = BT 470 BG = BT 601\_625. BT 2020 can be $BT 2020\_NCL$ (non-constant luminance) or $BT 2020\_CL$ (constant luminance). NCL is the standard.
