Lunaline background color right under window separator of Nvim-Tree

[MKrbm]

How can I set surface0 instead of mantle color here?

:h hl-StatusLine:

							*hl-StatusLine*
StatusLine	Status line of current window.

When I focus on nvim-tree, the color will set on the target part of Lualine. But when I focus on the editor, then not.

When editor window is focused

When nvim-tree is focused

For filetype-specific extensions/highlights, u need to modify lualine's components directly:

nvimdots/lua/modules/configs/ui/lualine.lua

Lines 20 to 48 in 8631738

	colors = require("modules.utils").get_palette()
	local universal_bg = require("core.settings").transparent_background and "NONE" or colors.mantle
	return {
	normal = {
	a = { fg = colors.lavender, bg = colors.surface0, gui = "bold" },
	b = { fg = colors.text, bg = universal_bg },
	c = { fg = colors.text, bg = universal_bg },
	},
	command = {
	a = { fg = colors.peach, bg = colors.surface0, gui = "bold" },
	},
	insert = {
	a = { fg = colors.green, bg = colors.surface0, gui = "bold" },
	},
	visual = {
	a = { fg = colors.flamingo, bg = colors.surface0, gui = "bold" },
	},
	terminal = {
	a = { fg = colors.teal, bg = colors.surface0, gui = "bold" },
	},
	replace = {
	a = { fg = colors.red, bg = colors.surface0, gui = "bold" },
	},
	inactive = {
	a = { fg = colors.subtext0, bg = universal_bg, gui = "bold" },
	b = { fg = colors.subtext0, bg = universal_bg },
	c = { fg = colors.subtext0, bg = universal_bg },
	},
	}

I think I've tried every single potential variables in the file but nothing affected this part

[Jint-lzxy]

Oh I see what u mean. In fact, this has nothing to do with lualine, it's:

							*hl-WinSeparator*
WinSeparator	Separators between window splits.

No, it's not effective unfortunately.
Maybe my explanation was unclear

I'd like to change the color of this area

The closest one was second picture of last post . But this one is not enough since this color is only applied when nvimtree is focused.

Thank you and sorry for taking your time.

This looks like the Normal background of nvim-tree itself. See :h nvim-tree-highlight
