Hi, How can a shape have a fill colour that is

- black if the diagram is viewed with light appearance.

- white if the diagram is viewed with dark appearance.

A shape can be given a line colour like that, by opening the Edit Style dialog and setting strokeColor=default in the key-value pairs.

If fillColor=default is set then the fill colour will be

- white if the diagram is viewed with light appearance.

- black if the diagram is viewed with dark appearance.

That's the opposite to what I want for some shapes.

Context is that I'm drawing UML activity diagrams. The start node should be a black circle, in light appearance, or a white circle, in dark appearance. Maybe there's another special value to which fillColor can be set? I couldn't find documentation of the possible values.

Cheers, Jim

Try fillColor=strokeColor or fillColor=default;defaultFillColor=invert
