I’m sorry Paul, I’m still inside a Covid cloud it seems. -context works with symbol-show and symbol-hide but not with symbol-colour, so it is not a solution to your problem.

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.

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.

I couldn't see a way of doing this.
