Yup, it's a crazy glitch. Exit out of Hopscotch and reopen, that usually fixes it!
I've had this glitch a few times. :D
Double tap the home button, then swipe up on hopscotch! :D

Sometimes get it. Try reselecting that color.
IT happens to me all the time!! Exit out of hopscotch and select a different color...if it works you can go back to grey
