[Therion] Best approach for colouring elevations

[Tarquin Wilton-Jones]

Hi folks,

With either extended or projected elevations, we end up with a few
passages overlapping each other. This is intentional (so displacing some
of them is not a desired solution). However, it would be nice to be able
to colour them differently, to make it easier to see which parts belong
to which passage. Colouring by altitude doesn't help in elevations,
because they are all at the same altitude when they are overlapping.
"Colour by distance from the viewer" is better.

This could be coloured by colouring the individual scraps, but that is
messy, and hard to maintain. The desired output would be "colour by
break". Meaning; each time there is a "break" in the map, change the fg
colour.

Does anyone have any tips on how best to colour extended/projected
elevations? Is "colour by break" possible in some way? Or do you prefer
a different approach?

Cheers,

Tarquin
