I know the design system and the logic behind the 5 colour approach is great, but I have projects where this logic cannot be fulfilled and I need more than 5 colours. So it would be a necessity for me to be able to add as many colours as I like in addition to the 5 and if I am not using the 5 colours I can also delete them (disable them) and use custom colours. The custom colours should also be able to handle dark and light and the other theme modes -> let me manually select a light mode and a dark mode colour.
