Hi guys!

I am trying to save a text file with the output of a Julia script but with the escape sequences so that I can render the colors. However, when I call Julia using pipe, I get no colors. Even if I have --color=yes. You can test by starting Julia as:

julia --color=yes | tee

The logo will be gray (but julia> will be colored). Is there a way to provide another option, like --color=force so that printstyled always use the escape sequences?

As a workaround, one can use:

screen -dm -L sh -c 'julia --color=yes teste.jl' && mv screenlog.0 output.txt

and then output.txt will have the colored output (with escape sequences).

- `--color=no` did not remove all color in the REPL
- color was not fully disabled by default when stdout was a pipe
- `--color=yes` did not enable color when stdout was a pipe (fixes #30703)
