You might want to use the colr atom then, adding options similar to:
-color_trc bt709 -colorspace bt709 -color_primaries bt709 -movflags +write_colr
just prior to your output filename, obviously you should select the
appropriate options, but those are usually a good starting point.

lor_matrix=bt709
almost all prores will expect to be bt709 for the colour matrix.

You may want to also try -vf scale=out_color_matrix=bt709 instead of
the colormatrix as that might give you better quality as ProRes is 10
bit, in addition to the options Carl suggested to write the color
atom.

In the ffmpeg documentation, there is:
vendor string - Override the 4-byte vendor ID. A custom vendor ID like apl0
would claim the stream was produced by the Apple encoder.
I am using this option but when opening the output file up in Quicktime 10
(Yosemite), the file shows the format as Lavc56
