output_styles

Every output's style with its default colour filled in.

Each drawn value output takes the series colour of its position among the drawn value outputs, whether or not it names a colour itself, so giving one output a colour never recolours the others. A hidden output is neutral and a zone is a pale accent. A usable state drawn as a background is the warning colour, a display-only background a pale neutral, and any other state or event the accent colour. An event that names both its up and its down colour and no colour keeps no colour: the two say everything.
