However, it doesn't support `%c`:\r\n\r\n```\r\n> console.log('%cHello World', 'color:green; background:yellow;')\r\n%cHello World color:green; background:yellow;\r\n```\r\n\r\nThe same code in Safari, Firefox, and Chrome does this:\r\n\r\n\u003cimg width=\"1225\" alt=\"Screen Shot 2019-09-18 at 3 55 58 PM\" src=\"https://user-images.githubusercontent.com/427398/65181697-9df56780-da2d-11e9-9867-4c0f172f3ec8.png\">\r\n\r\nThe [Console spec doesn't give a ton of help on what `%c` should do](https://console.spec.whatwg.org/#formatter), other than to say that it \"Applies provided CSS.\"\r\n\r\nObviously there are aspects of this that don't make sense in the terminal vs. a browser, but perhaps some of it does?  It would be nice if node's `console` could do more than ignore `%c`.\r\n\r\nApologies if this has come up in the past and been rejected.  I wasn't able to find a previous discussion.","author":{"url":"https://github.com/humphd","@type":"Person","name":"humphd"},"datePublished":"2019-09-18T20:07:09Z","url":"https://github.com/nodejs/node/issues/29605"}
