Roll20 recently updated to keep all of the dice outlines in the chatbox blue for readability, rather than each player having their own chosen color shown. While this is a fantastic update for people who struggled with readability in the log, my group has colors assigned to each character they play, and as a GM it was much easier for me to see who had rolled by looking at the colors of the dice (we often have multiple characters rolling at once, particularly with observation checks or dodging enemies/taking damage), since the names all look the same at a glance and the visual dice are bigger and easier to see. I would like to suggest making this a toggle setting - similar to how players can choose whether or not they want the 3D dice to roll on their screen, they can choose whether or not they want the colored dice in the chatbox. That way, those who need everything uniform can keep the default blue and those who differentiate characters by color can have it match the players' hex codes.
