Have you checked the documentation? You can specify the color for the "pad"
filter:
https://ffmpeg.org/ffmpeg-filters.html#pad-1

$ [...] [0:0]pad=140:70:color=red[t1]; [...]

Interesting command. You supply three input files, but use only two.
And you "force" the first one to be recognized as GIF, while the others
are automatic. Any reason for this? (Just trying to help.)
