Verifies whether each input line contains a valid three- or six-digit hexadecimal number, commonly used as color codes in CSS and other technologies. Each number must begin with the "#" sign. I've seen other regexes for this which use individual expressions for a three-digit number and a six-digit number as alternates for each other.
