Update 4.0:
Meanwhile I've been working on both maps. Mauve is waiting on the final checks - after another discussion with @Leto_II the map will shortly be available in both the FAF and LOUD map vault. Once that happens there will be another post with all the PR pictures to make it shine.
In Autumn, the map of Blodir, I've been studying the color nodes of World Machine. Add some experimentation to that and we have a breakthrough.
My understanding has increased a lot - these rocks are made out of a new color network that provide more control and flexibility. It is now a lot easier to fine-tune the colors. Throughout the week I'll be experimenting with various other places to add in colors such as for area's with rocks, trees, or roads.
This will allow me to tune the map a lot more - area's that have trees on them will have a different color pattern / properties than area's that had rocks on them. It will be easier to add visual cue's to critical gameplay elements, such as ramps.
edit: all the images taken are from the GPG editor, not the Ozone that makes them look slightly better.
