[FFmpeg-user] White Padding Looks Gray

I'm an ffmpeg beginner experiencing an issue with adding white padding to a
video straight out of a 5D Mark III. Our workflow is to capture via EOS
Utility and a tethered camera, which yields a MOV file (a.MOV) - I'd then
like to rotate that file and center it in a square frame with white
padding. I don't need any audio.
Whenever I run this command, however, I get a light gray instead of white
in the padding area.
It's quite similar to this situation:
http://video.stackexchange.com/questions/16682/ffmpeg-white-padding-is-light-grey-but-not-white
- but in my case, I need a video output, not stills.
*command:*
ffmpeg -i a.MOV -codec:v libx264 -profile:v high -preset slow -b:v 500k
-maxrate 500k -bufsize 1000k -vf
"transpose=2,pad=1920:1920:420:color=White" -threads 0 -an k.mp4
*console:*
