The colors used to work on macOS and were broken on Linux, now it's the reverse (see CI checks).

@sw

I don't have access to a Mac. Can you please try these for me?

echo -e '\033[36mrun ./main -h for help\033[0m'

printf '\033[36mrun ./main -h for help\033[0m\n'

I can confirm both of those options are fine on Linux.

Me neither, but I don't think using octal instead of hex is going to do the trick. If no one else can check this on macOS, you may push the printf variant which looks fine to me, then we can run the CI again.

@sw An alternative approach would be to special case it and have different behavior based on whether or not it was running on Mac.

Personally, I don't love the idea of my Makefiles spitting out escape codes in the first place so I'd also have no problem with ripping out that part and just making it a normal line of text. There are other ways to make it stand out like with blank lines.

==== run ./main -h for help ====

Or something along those lines. That approach also works better for people with stuff like colorblindness. What do you think?

edit: I just went with that approach.
