Hi! @am-bui @corinnesollows Love these CLI changes.

Naïve question: how does one switch between dark and light modes?

[adam-alula]

I'm with @mjgiarlo wondering how I utilize light mode. I cannot read the help menu anymore in my terminal which uses a light theme. The border also wraps poorly if a terminal is only so wide.

Yes, that is the same boat I'm in. In the meantime, you can prefix TESTING=true to the CLI command to get back the old menu.

@adam-alula As best I can tell, this is handled entirely automagically via the termenv library---I can't find any switches, environment variables, or configuration to vary this as a CLI user. You can see termenv's support for various terminals here: https://github.com/muesli/termenv#optional-feature-support (As a tmux user myself, this is a bit of a bummer, but TESTING=true is good enough for me.)

@mjgiarlo setting TESTING works for now. I will create an alias and cross my fingers until I have to address this again. Thank you for the insight into the problem!

@adam-alula While spelunking in the termenv library, I discovered the COLORFGBG environment variable which it can use to determine whether the terminal has a dark or light background. My terminal doesn't set it by default, so I figured why not try it?

So to "force" light mode:

$ COLORFGBG="0;15" circleci help

or dark mode:

$ COLORFGBG="15;0" circleci help

Works for me, anyway. Though note that these will be using ANSI colors, so it's not super colorful but the text is at least visible.
