This is a command line utility that is a wrapper for setting colors in Linux shells/consoles/terminals/ttys; whatever you want to call them.

This essentially replaces something like; (given alias sc='setcolors'): '\033[1;31mText\033[0m' with something like: $(sc 1 31)Text$(sc), but this is just a very basic example as this can be used programmatically and can be passed arrays. You can find more examples on this page.

This will not override any normal color stuff you have going on in your environment just as if you were using escape sequence colors in the same way.

You have 3 options here; 1 installable .deb file or 2 portable executables: binary & an AppImage.
