Set color to the components:

Using icons as indicators

If you would like to replace the default indicators with symbols like on the screenshot, then you'll need to ensure you have some "iconic fonts" installed, such as Font Awesome. A common alternative is to replace your primary font with one of the Patched Nerd Fonts, which saves you from having to install multiple fonts.

The following icons from the Font Awesome font are used in the screenshot:

Hints: f002
Infos: f129
Warnings: f071
Errors: f05e
OK: f00c

To specify icons in the configuration, use their unicode codes as "\uXXXX" (make sure to wrap them in double quotes). Alternatively copy the icons from a font website, or type <C-v>u<4-digit-unicode> or <C-v>U<8-digit-unicode> to insert the literal characters.

See the code points here:

Font Awesome: https://fontawesome.com/icons
Nerd Fonts: https://github.com/ryanoasis/nerd-fonts#glyph-sets

Here's the configuration snippet used in the screenshot:

let g:lightline#lsp#indicator_hints = "\uf002"
let g:lightline#lsp#indicator_infos = "\uf129"
let g:lightline#lsp#indicator_warnings = "\uf071"
let g:lightline#lsp#indicator_errors = "\uf05e"
let g:lightline#lsp#indicator_ok = "\uf00c"
