How do I change my custom view's text color?

[andradei]

I copied the cmdline_popup and modified it for when macros are being recorded.

After getting lost in the docs between views, formats, and routes, I still don't know how to:

• Change the text color from green to red (see screenshot)
• Add icon and title to the floating window like this:
  

My config

return {
  lsp = {
    -- override markdown rendering so that **cmp** and other plugins use **Treesitter**
    override = {
      ["vim.lsp.util.convert_input_to_markdown_lines"] = true,
      ["vim.lsp.util.stylize_markdown"] = true,
      ["cmp.entry.get_documentation"] = true, -- requires hrsh7th/nvim-cmp
    },
  },
  -- you can enable a preset for easier configuration
  presets = {
    bottom_search = true, -- use a classic bottom cmdline for search
    command_palette = true, -- position the cmdline and popupmenu together
    long_message_to_split = true, -- long messages will be sent to a split
    lsp_doc_border = false, -- add a border to hover docs and signature help
  },
  views = {
    virtualtext = {
      hl_group = "LspInlayHint",
    },
    -- Custom view for macro recording.
    macro_recording = {
      backend = "popup",
      relative = "editor",
      focusable = false,
      enter = false,
      zindex = 200,
      position = {
        row = 3,
        col = "50%",
      },
      size = {
        min_width = 30,
        width = "auto",
        height = "auto",
      },
      border = {
        style = "rounded",
        padding = { 0, 1 },
      },
      win_options = {
        winhighlight = {
          FloatTitle = "NoiceFormatLevelError",
          FloatBorder = "NoiceFormatLevelError",
        },
        winbar = "",
        foldenable = false,
        cursorline = false,
      },
    },
  },
  routes = {
    -- Show macro "@recording" when q-<register> is pressed.
    {
      view = "macro_recording",
      filter = { event = "msg_showmode" },
    },
  },
}
