In e.g. #251 there has been some confusion about list colors not showing. We could:

• document this (https://todoman.readthedocs.io/en/stable/configure.html#color-and-displayname)
• add a command that will output test colours

or, alternatively:

• round colors to the next 16-bit color for terminals that don't support it. This will loose colour information, not sure if desirable
