All color options don't work except `pink`

[CoolDove]

When color is not pink, invoking the hydra will cause this error.

Even the configuration in sample has this problem. Sample Vim-Options

Here is my config:

Hydra = require('hydra')
Hydra.setup({})

Hydra({
	name = 'Paste Ring',
	mode = 'n',
	body = '<M-n>',
	config = {
		color = 'red',
		invoke_on_body = true,
		foreign_keys = nil,
		exit = false,
	},
	heads = {
		{ '<C-n>', "<Plug>(YankyPreviousEntry)" },
		{ '<C-p>', "<Plug>(YankyNextEntry)" },
		{ '<Esc>', nil, { exit = true, desc=false } },
		{ '<C-c>', nil, { exit = true, desc=false } },
	},
})

When i change red to pink, it will work but foreign keys won't close the hydra (foreign_keys got overwritten i guess). And i'm curious why the color field got designed, i think it's better to just set the two fields individually.

I have the same issue. Is there any solution
