Color Difference on ffmpeg Outputs

Mark Scott
I noticed a color difference between my master video file and the
output file from ffmpeg. My master file is Apple ProRes 422 HQ .mov. I
converted it to Apple ProRes 422 (not HQ).mov, using ffmpeg. There is
a significant color difference on the converted file that is
noticeable in the graphics.
The RGB values are: Master file: R:221 G:49 B:42  Converted file:
R:202 G:24 B:32. All lower numbers on the converted file. I'm
attaching a screenshot to show the difference. Is there a filter or
something that I can add to this command line to solve this?

mkdir outputs
for f in *.mov; do ffmpeg -i "$f" -c:v prores -c:a pcm_s24le
"outputs/${f%.*}.mov"; done

Please provide the actual command line that you tested (without
variables) together with the complete, uncut console output and
please remember that only current FFmpeg git head is
supported here.
