   I was trying to establish what colors would be reasonable there.

   How many colors does that terminal support?

16 colors from what I understand.  list-color-display shows:

  black                black  #000000
  red                  red  #ff0000
  green                green  #00ff00
  yellow                       yellow  #ffff00
  blue                 blue  #0000ff
  magenta                      magenta  #ff00ff
  cyan                 cyan  #00ffff
  white                white  #ffffff

I'd think that magenta would make most sense, but that would require
changing what is used for eshell-ls-archive?
