# forge.indicator.output_styles

```python
forge.indicator.output_styles(source: type | Sequence[_OutputDecl]) -> dict[str, PlotStyle]
```

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.
