How do we make this a feature request then?

You can make a feature request in the Issues section of this repository, but I do not think that this specifically is a worthwhile feature request.

We primarily use the standard 8 ANSI colors for color output from gh. Our tool offers no color customization, but almost any terminal emulator offers customization of these 8 basic colors via its terminal color scheme. What that means is: if you customize your terminal background to be blue, you should also customize the blue and cyan colors output so they are visible on a blue background. In other words, the user is in complete control of their terminal color scheme, not the command-line tool itself.

However, Command Prompt on Windows is not a full-featured terminal emulator, as it doesn't support the base 8 ANSI colors, and its color customization options only offers you to customize the background color and the primary text color but not any other colors. That means that if you change your Command Prompt background color, you are at risk of some other colors now blending in with your new background color. I would suggest not changing your Command Prompt background color if you also use command line tools that output color. Or, you can disable color output from gh completely.

If you do want the ability to be in full control of the terminal color scheme, I would suggest switching to Windows Terminal which is a free, fully-featured terminal emulator for Windows made by Microsoft. It allows you to completely control the color scheme that you see and avoid the blue as output from gh blending with a similarly blue background.

This does not appear to be the case though. gh appears to be using some escape sequence that is not part of the standard 8 or even 16 ANSI colors, and I don't think most terminals provide a way to control these colors (my iTerm2 on mac included). Please see my screenshot that seems to show the prompt is none of the main normal or bright ANSI colors and I seem to be able to create the same color (or come close at least) by using the escape sequence 38;5;59. Replacing the last number with something between 239 and 244 also comes very close.

@mislav, update: I figured out how to enable screen recording in iTerm2 and it turns it that gh is emitting the escape sequence <esc>[38;5;242m before that prompt. If this pretty darn dark grey is not already visible on whatever color I choose for my terminal's background color, there is nothing I can do about it.

By the way, to give some context, this was more than just an annoyance for me at first. I was trying to figure out how to use the gh command and what it could do, and I tried to use it's edit functionality. I usually have a cursor guide setup in my terminal, and with that enabled, the existing title string in the prompt was nearly invisible. I couldn't tell that it was there. I hit enter thinking it would give me a chance to then edit the title in my editor, and was immediately prompted with "Submit?" and with the unedited title now suddenly visible.

UPDATE: I created a candidate fix for this - I don't know if it is the best choice for what color to use, or if the designers/devs might want to make it more intelligent and decide which color to use by first detecting the background color of the terminal (if that is possible), but it has to be better than that dark grey color for most users. Here is the change: #7354
