Describe the question

I know I can use the base 16 colors (color0-color15) in yazi's theme.toml. However, these colors do not include the following colors:

• background
• foreground
• cursor

We do have escape sequences to query them.

Why do I need it?

I want to make a base16 flavor for yazi where I don't want to hardcode the background value.

So far, I got up to here but I can't think of a way to fix the separator.

[mode]
normal_main = { fg = "blue", bg = "reset", reversed = true, bold = true }
normal_alt = { fg = "blue", bg = "black" }

Anything else?

No response

Checklist

• I have searched the existing discussions/issues

If you want to use the terminal default background, just do not set the bg, since it's already the default:

- normal_alt = { fg = "blue", bg = "black" }
+ normal_alt = { fg = "blue" }

fg is also the same

[UtkarshVerma]

normal_alt is fine in this case. What I want to address here is that normal_main should by styled like so:

• fg = terminal's background
• bg = blue

But when I do this, the separator starts behaving weirdly.

[sxyazi]

Why would you want to set the background as the foreground color?

I don't think that's possible. OSC 11 responds to RGB colors, but you want base16 colors, and not all terminals support OSC 11.

[UtkarshVerma]

Basically, I want to reverse the foreground and background colors for the mode indicator, since that is how the UI should be.

In this case, everything works. Is there a way to ensure that the separator is styled correctly too? I want it to be blue, just like normal_main
