title: ImageJ/Fiji change the default colormap
body: <p>Is there a way to change the default colormap in ImageJ/Fiji?
  Maybe it is too obvious but I didnt spot it in the options.
  Or is there a way to run a script automatically after an image has been opened and the script does for example: run("Fire") ?</p>
  
  <p>Cheers </p>
