Setting Icon Color?

[bennypowers]

How Do I set the color of an icon? I want to have blue directory icons:

renderers = {
  directory = {
    {
      "icon",
      folder_closed = "", -- how do i colour these?
      folder_open = "",
      padding = " ",
    },
    { "current_filter" },
    { "name" },
    {
      "clipboard",
      highlight = "NeoTreeDimText",
    },
    { "diagnostics", errors_only = true },
  },
},

It's going to use the NeoTreeDirectoryIcon highlight group for that. Just set that group to change the color. I use these settings for directory:

      vim.cmd([[
      hi link NeoTreeDirectoryName Directory
      hi link NeoTreeDirectoryIcon NeoTreeDirectoryName
      ]])

Is there an easy way to make all icons monochrome?

I think it will work if you configure nvim-web-devicons to not use colors: https://github.com/nvim-tree/nvim-web-devicons#setup

require'nvim-web-devicons'.setup {
 -- globally enable different highlight colors per icon (default to true)
 -- if set to false all icons will have the default icon's color
 color_icons = false;
}
