Is there a way to change the inlay hint color?

[tubzby]

I'm using nvim with rust-analyzer, the text ": Cli" and ": u16" are inlay hint texts.

I prefer grey color for 'inlay hint color', is there a way to do that?

Can you give some more information, such as:

• Neovim or vim?
• If neovim are you using treesitter?

If you are using neovim and treesitter you could use treesitter-playgroud to see what highlight grop the thing you want to change, and then use hi! <highlight> guifg=<color> guibg=<color> to change the highlight.

I'm using Neovim 0.8.1 without treesitter.

Hi there, I think you will need to follow the advice above and try to figure out which highlight group that hint texts are. Once you know, you can try editing the colors for that specific highlight group. Unfortunately, it might happen that they share the same group with another syntax, in which case it'll be hard to differentiate them in vim.

@tubzby assuming you're using rust-tools you can set the highlight group for the inlay e.g.

local rust_opts = {
	tools = {
		inlay_hints = {
			highlight = "rustInlayHint",
		},
	},
}
require('rust-tools').setup(rust_opts)

Then you can set the colour as normal, e.g.:

highlight rustInlayHint ctermfg=235
