Hello,

Using the following command to put two images together:
montage -mode Concatenate -frame 5 -tile 1x2 mostemp.24.gif mospop.24.gif mos24.gif

This was working fine, but after I upgraded to 6.9.1-7 via yum update (remi repo) under CentOS 6.6 the image colors started getting weird with black replacing certain colors where it shouldn't .

For reference, here are the images I am combining:
http://vortex.plymouth.edu/mapwall/mospop.24.gif
http://vortex.plymouth.edu/mapwall/mostemp.24.gif

and the result
http://vortex.plymouth.edu/mapwall/mos24.gif

You should upgrade to 6.9.1-8, that version contains a flaw in the GIF writer. The same issue was reported also here: viewtopic.php?f=3&t=28013
