I have managed to get some effect from ‘select map -colour’, but not entirely the desired effects.  Just documenting the behaviour here…

There are no lookups defined in this project.

select AblutionInceptionPlanMap -colour [0 0 100] #blue

select QuackeryPlanMap                -color [0 100 0] #green

select SouthBoundPlanMap           -color [100 0 0] #red

The above selects have no effect, the maps are all uncoloured, unless…

I add, ‘colour map-fg map’, inside a layout, then I get all maps coloured with the last colour specified (red)…

I wasn’t expecting ‘colour map-fg map’ to have an effect, as I thought the ‘select map -colour’ would override layout specifications, or at least have the option to override (to make it both ‘easy’ and allow combining other colour palettes (such as map-fg explo-date) with particular maps highlighted and overriding the palette).

If I change the order of selects, I find the last colour selected is the one that colours all the maps.  Eg, making green last colours all maps green.

If I make all of the spelling consistent, ie color, or colour, there is no effect.

If I add other select map statements with no -colour option, then, again, all maps are coloured with the last colour selected.

If I remove the -colour option from select statements, and use only ‘colour map-fg map’, then I get appropriate automatically coloured maps, ie
