How does tealdeer's color configuration interface with a terminal's own color scheme? #224

Closed bound-variable closed 2 years ago

bound-variable commented 2 years ago

I'm using Guake. I realized that the colors in tealdeer's config don't appear, e.g., cyan doesn't appear as cyan. So I looked into my terminal's color scheme and found that by changing the scheme, tldr's colors also changed. So, is there any information on how these sources of color schemes interact? It seems there's no point in my changing tealdeer's config because the terminal's color schemes significantly alter the intended results.

Thanks

If your terminal uses a theme that changes the appearance of colors, there's not much that we can do about it, right?

In the end, colors in the terminal are ANSI escape sequences mapped to color names. How these color names are displayed to the user is up to the terminal.

I understand that this is not an issue the developers of this program can resolve. I was merely asking for information on how they interface with one another. I was under the impression that all terminals use some sort of color scheme. Given that, it seems there's no way to render a terminal program with an intended set of colors, since the terminal will always modify those colors. Or perhaps there's a universal default color scheme? I don't know.

If a terminal application outputs something with the escape code 32;42, this is documented as "green". uxterm uses a very bright, "grassy" green while alacritty uses a more yellowish, softer green. But both are green. There's no other specification how "green" should look like.

Of course the terminal or a theme is free to remap colors as it desires, but it may leave users (as you) confused. The terminals I know usually don't do that.

Got it. Thanks again.
