Hi Bruce, Yes, I was wanting to change a specific instance. These are great tips. Using the colour of another point type that I'm not using, then changing the context for other specific points, would be a simple hack that I think would cover me.

Hi Paul
If you are asking if it is possible to change the colour of a specific instance of a particular type of generic object, I think the answer is no, unless you modify the metapost definition for the generic object to allow attributes such as colours to be parsed.
If you want all of a generic object type to be a colour, then use a layout statement something like:
symbol-colour point label <colour>
Easy hacks to mimic the first question include…
Use point remark and set its colour to something striking with:
symbol-colour point remark <colour>
You can change the fonts to add or remove emphasis.
Or use -context to make the label inherit colour as though it were another type of symbol…
point label <x> <y> -text “label text” -context point anastomosis
and
symbol-colour point anastomosis <colour>
I suspect not all point types work with -context, so you may have to hunt around to find one that works.

Is it possible to change the label and/or passage height colours for specific points? I couldn't see a way of doing this.
Thanks,
