ANSI color codes working inconsistently/incorrectly in terminal

[j0hnm4r5]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.69.2
• OS Version: macOS 12.1

Steps to Reproduce:

1. Clone & install this Node.js repo
2. Run npm run start in both VSCode and your OS's built-in terminal

This is a screenshot from VSCode:

This is a screenshot from iTerm2:

As you can see, VSCode isn't rendering the text as blue when it is on the red background (or any other color for that matter), but it is rendering the text as blue when it is on the black background. In iTerm2 and Terminal, everything renders as expected.

This is the case across all themes, from what I can tell.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.69.2. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

Sorry, that was a typo — I've updated with the correct version. Issue still persists.

This is very interesting — when printing ANSI codes raw in the terminal (generated here), some of the text color is poking through but it is very muted (as if the background color is actually overlaying the text or the text is transparent).

Using a color picker in the center of one of the Xs on each line, this is what the actual colors are rendering as:

• MAGENTA TEXT -> rgb(212, 113, 217)
• MAGENTA TEXT / GREEN BG -> rgb(79, 41, 81)
• GREEN BG -> rgb(6, 63, 41)
