bug: With default configuration I am getting different visuals

[Divyanshg01]

Neovim version (nvim -v)

0.10.1

Operating system

Arch Linux

Terminal emulator / GUI

Kitty terminal with zsh

Describe the bug

When I load the default config and open the markdown files, all the heading except level 1,2 are in red color I don't know why it is

Expected behavior

It should be of different colors and the code blocks are also of different color(black) instead they should be transparent

Additional information

I am using it with obsidian.nvim but I don't think this behaviour is caused by it still I am providing my obisdian.nvim config

return {
    "epwalsh/obsidian.nvim",
    version = "*", -- recommended, use latest release instead of latest commit
    lazy = true,
    ft = "markdown",
    -- Replace the above line with this if you only want to load obsidian.nvim for markdown files in your vault:
    -- event = {
    --   -- If you want to use the home shortcut '~' here you need to call 'vim.fn.expand'.
    --   -- E.g. "BufReadPre " .. vim.fn.expand "~" .. "/my-vault/*.md"
    --   -- refer to `:h file-pattern` for more examples
    --   "BufReadPre path/to/my-vault/*.md",
    --   "BufNewFile path/to/my-vault/*.md",
    -- },
    dependencies = {
        -- Required.
        "nvim-lua/plenary.nvim",

            workspaces = {

                    path = "~/Documents/Notes",

Not a bug, just the default behavior.

We use the highlight groups RenderMarkdownH1Bg .. RenderMarkdownH6Bg for the backgrounds.

In the colors section of the README: https://github.com/MeanderingProgrammer/render-markdown.nvim?tab=readme-ov-file#colors, if no values are defined by your color scheme for these highlight groups then RenderMarkdownH3Bg .. RenderMarkdownH6Bg all link to DiffDelete.

You can either:

• Use a color scheme which directly supports this plugin like tokyonight, catppuccin, and several others
• Define RenderMarkdownH3Bg .. RenderMarkdownH6Bg as whatever colors you like

• Provide different highlights for the backgrounds: https://github.com/MeanderingProgrammer/render-markdown.nvim?tab=readme-ov-file#headings

  require('render-markdown').setup({
    heading = {
        backgrounds = { 'highlight_1', 'highlight_2', 'highlight_3', 'highlight_4', 'highlight_5', 'highlight_6' },
    },
  })
