UML25 — color of the notation is specified

In the UML spec there are several places where the color of the notation is specified. For example, the composition diamond is specified as black, the state machines junction ball is specified as black, and the lost/found message is specified as black, and the information identifier is a black triangle.

Similarly there are few cases where white and grey are specified.

This is overly limiting, some tools use a solid color for the items specified as black, or let the user select the color (usually selecting the same as the line color). It would not be good to limit the representation to only black color, as that would invalidate most PowerPoint and several tools.

Please change the color black to “solid” or “filled with the line color” and change “white” to “hollow” or “un-filled”.

For grey/gray it should be “a distinguishable value between the solid and the hollow”

Put some clarification into “How to read this specification”.
