It's how Wordle represents my result apparently (I didn't understand it myself but it is similar to other postings above). Edit: Now you mention it, the "result" that Wordle gives you to "share" looks much more sensible when you first Paste it into the forum "reply" box - a mix of different colour boxes indicating "Definitely NO; Yes but wrong place and Yes in right place". But as soon as you commit your reply it changes to those unrepresentative purple boxes.
So why don’t you try the emoticons = no = yes but wrong place = yes and right place = only for entire correct answer
