Suggestion: option for roles that let individuals change their own color

I see many servers have messages with lots of reactions that you can react to to get a certain role that changes the color of your name in chat, most times with a bot, some times manually, an I think it'd be nice if you can toggle an option for a certain role, and if that role is the role that would show color (same way normal roles show the color in your username of your highest priority role) you could change the color. This could work similarly to /nick to change your nick name but you could maybe type /color and type the hex color value or right click your profile while in the server and below "change username" might be an option to "change color".
