Comment (by Leo Izen):

 This is caused by the automatic converstion from rgb24 to bgr8, which is
 the default for the gif encoder. bgr8 cannot represent the colors
 correctly. Use this instead:

 ```
 ffmpeg -i spiral.png -vf 'split[v],palettegen,[v]paletteuse' spiral.gif
 ```

 The original picture only has 60 colors so this shouldn't create any loss.
