Can anyone explain to me why this displays only the yellow bar with

ffplay -f lavfi -i 'smptehdbars=duration=5' -vf
"colorhold=color=0xbcc906:similarity=0.25,chromakey=color=black:similarity=.2"
but this displays all bars in gray scale except the yellow bar which is
in color:
ffmpeg -f lavfi -i 'smptehdbars=duration=5' -vf
"colorhold=color=0xbcc906:similarity=0.25,chromakey=color=black:similarity=.2"

What I want is ONLY the yellow bar and everything else black, as in the
ffplay command. How can I get the same thing with ffmpeg?
You need to also use the overlay filter.
Can you expand on that a bit? What am I overlaying? I only have one
input.
And why does the above command work using ffplay, but not ffmpeg?
