r147 adds support to mp4track tool to manipulate COLR.
Example usage would be:

# list colr-boxes, if any
mp4track --colr-list test.m4v

# remove colr-box from all appropriate tracks
mp4track --colr-remove test.m4v

# remove colr-box from track-id=1
mp4track --colr-remove --track-id=1 test.m4v

# add colr-box of default type to tid=1
mp4track --colr-add --track-id=1 test.m4v

# add colr-box of same parameters which HB uses for HD content
mp4track --colr-add --track-id=1 --colr-parm-hd test.m4v

# add colr-box specifying all 3 indexes manually
mp4track --colr-add --track-id=1 --colr-parms=1,2,3 test.m4v

the values for colr-parm-hd and colr-parm-sd are switched (SD should be 616, HD 
should be 111, see 
http://forum.handbrake.fr/viewtopic.php?f=4&t=6352&p=41489&hilit=colr#p36397). 
Attached is a patch 
against r150 to fix this. 

Tested and works as expected now, only part I was unsure about was if the reset 
function should be patched to 
have 616 instead of 111 as well, and I assume the reset function errs on the 
side of assuming SD material, so I 
did change it.

patch applied in r155... that is unless i borked something again as r155 was 
rather large.
