Dark Mode Colors need vibrant option

The colors of events\tasks, etc, in dark mode should be the same as in light mode. I have specific colors for projects and tasks. This all works fine in light mode (orange = orange and yellow = yellow). However, in dark mode, they are completely off (orange = dark brown and yellow = tan). Please include a dark mode option that uses true, vibrant colors so we can easily differentiate, since color is essential in a task manager.
