Event Color Separate From Category

It would be better if I were able to choose the color of the event regardless of the category it is in. Colors should be separated from the categories. For exaple, if I were to have a very important event, I would want it to be color red (because it is very important) regardless of the category it's in. People have different ways of associating colors, whether it's because of it's importance, a personal coloring sistem or simply for the visuals of it. Therefore colors should be a choosable feature separated from the category of the event.
