Q: Why color highlight is not shown on my vim?

A: First, make sure "coc.preferences.colorSupport" is not false in your coc-settings.json, then make sure you have set termguicolors in your .vimrc, and your terminal support true color.

Q: How to change highlight of the current symbol.

A: All you need is overwrite the highlight group, checkout :h coc-highlights
