Right now we have the option to have today's event background color and the other days in a single background color as well, but there is not an option to have today (background color gray), tomorrow (background color darker gray) and the rest of the days (background color black) there is an option for 2 only and the reason why I like it with 3 is because it helps me the day before to visualize more comfortable what's going on the next day.

Thanks
