Suppose that you are tasked with writing a new website for a client. After completing the website, the client remarks that the website looks good, but they ask if you can implement a feature for forms where the "submit" button is highlighted green when the form is fully filled out, yellow when only the required information is filled out, and red when one or more required items is missing. Is this a good design from an HCI perspective? If so, why? If not, what is wrong with it? Justify your answer.
