<input type="color"> - HTML: Hypertext Markup Language
WebHTMLElementinputcolor
because users can write colors in many different ways (such as rgb(255, 255, 0)), one way to work around this is to set a pattern attribute equal to either #[0-9a-f]{6} or #[0-9a-fa-f]{6} (preferably the latter because some users may not expect a different result with just a letter-case change) and set a placeholder attribute equal to a color representing the expected format of the user's input, such as #ff0000.
