Being the rgb profiles in 'tmpfile', the option rgb | bgr | ... would choose
this order:

plot 'tmpfile' \
  u 1:2 title 'red'w l 1, ''u 1:3 tit 'green'w l 2, ''u 1:4 tit 'blue' w l 3

or this one

 using 1:4 'blue', u 1:3 'green', u 1:2 'red'

or ....

In principle, it select which color curve will be on top if (at least) two
overlap like e.g. in 'palette gray' (all 3 r,g,b profiles overlap).
