Comment (by rmk):

 I just noticed, I made a copy & paste error in the ticket. The first step
 (generating the broadcast range file) should be this instead:
 {{{
 ffmpeg -f lavfi -i nullsrc=s=256x256 -vf geq='16+220*(X/W):128:128'
 -pix_fmt yuv420p -vframes 1 -c:v ffv1 -y ~/tmp/colortest/gradient-
 broadcast-range.mov
 }}}
