When determining colours of categorical variables in uns they are based on alphabetical order (if I am not mistaken) - being represented just as an ordered list. Thus it is a bit inconvenient to change colours, especially if categories change during the analysis - the whole order changes and the mapping breaks. Would it be possible to use a dictionary of colours as values and categories as keys (with a default for any categories missing colours)?

Research direction
The issue names no files, tests, or entry points. Start by locating where categorical colours in uns are assigned and represented, then check how category changes affect that mapping. Done means colour dictionaries can use categories as keys while missing categories receive defaults.
