There's a word in English that first meant "dark blueish gray, like lead," and that's "livid."
Depending on your skin tone, if your face seems to turn that color, it probably means you're extremely angry. And so, over time, the meaning of the word "livid" grew more specific. If you're livid, you're so extremely angry that it's as if your face is the deep, dark color of lead.
"Livid" means the same thing as "very mad," "furious," and "outraged." But it's a more serious, more formal kind of word.
So, when you need to sound pretty serious as you're talking or writing, then refer to people as livid if they're really, really mad.
