Thank you for reporting this! Should be easy to fix, I hope.

Well what I realized is that no single color will work well, depending on whether a user has a light or dark background. I imagine this is part of why there were once separate ansi-dark and ansi-light themes.

FYI @mk12: again, only if you are interested(!).

Can you share an example of when bat would use this? I'm not sure when a line would be highlighted.

Ah, yes. Sorry. Whenever someone uses the --highlight-line option:

    -H, --highlight-line <N:M>...        Highlight lines N through M.

For example:

seq 10 | bat --highlight-line 3:5

Thanks for the example, I didn't know about that.

Even if ansi-light and ansi-dark were still separate I don't think there's any good color for this in a typical 8 color palette. For example if you choose yellow then foreground yellow text becomes invisible. You could choose from the 256-color palette but that defeats the purpose of ansi being restricted to the 8 color palette.

I'd suggest using bold (already supported I believe) or reverse video (would need to use another alpha channel pattern to encode it). What do you think?

What's the support for underline like? I imagine it's less common in terminal emulator than bold.

Yes, definitely.

Let's try this out.
