It accepts the following values:
@table @samp
@item gray
@item tint
Gray values are displayed on graph, higher brightness means more pixels have
same component color value on location in graph. This is the default mode.

@item 709
@end table
Default is auto.
@item tint0, t0
@item tint1, t1
Set color tint for gray/tint vectorscope mode. By default both options are zero.
This means no tint, and output will remain gray.
