This is totally beyond my understanding ... the below attached file is the GJ2.1_Night_sky2.ZIP scheme, which differs to Abb's scheme GJ2N_sky_v2.zip (two post above) only by the color.ini.
The only difference is in GJ2.1_Night_sky2.ZIP/color.ini, three sections for [clip_planes] with same parameters but different values are presented while in GJ2N_sky_v2.zip/color.ini, there is only one section of [clip_planes].
NOW THE SURPRISE: In Abb's scheme, the expected GREEN planned_routed is shown, in mine scheme, it is shown as black!!! 


Anyone? 

One of the three [clip_planes] sections, same parameters with different values:
[clip_planes]
; mode, lower bound, upper bound, lower value, upper Value
; mode: 0: by zoom level, 1: by number of cells, 2: by intersect value (0..45)
; values: 0.0 .. 1.0 * 1000 (= 0..1000)
