Is it possible to ask for more & better control over the use of colour? One of the ways in which this is useful is in allowing viewers to quickly match the same parts of a cave between plan and elevation. This can be done in a straightforward manner if you have one plan and one elevation as the maps (in colour by map) can be placed in matched order and so get allocated the same colours in sequence. Where one has more than one elevation, however, in the example I am working on we have three different elevations all on different projections. Different maps are used for each and, obviously, they do not get the same full set that the plan gets. Colour matching thus becomes impossible except by using cheats of such complexity that my brain fell over. The final match can be done in an image editor, I imported my final pdf into Gimp, did the match & exported it as a pdf again (Gimp can be recommended for this) but it would be nice to be able to control the whole process in Therion.
