I used wayback to check 270toWin from 2014, sure enough they had NC colored light blue back then. I also checked 2018 and they had Florida and Indiana as light blue. I checked for late October (25th or so) of those years. Couldn't do earlier years because of Flash plug-in.
Just an FYI in 2014 Tillis was DOWN 5 points in literally every single poll... He still won.
