Maybe this exists and I just don't know it. But while working on pak.Excentrique, I noticed that the relief map shows ground in green, regardless of the real ground texture or color. I guess this works for most paks, but in pak.Excentrique the mismatch becomes quite apparent.
It'd be nice if the relief map could take the colors automatically from the ground/climate textures, but it would also work for me if I could configure the colors somewhere, to match my ground textures.
Maybe add the use of MapColor= parameter in dat file?
This can work if exist or at least it can be a suggestion for next Simutrans. ;)
MapColor currently (IIRC) only allows one of 255 fixed colors. And it's not allowed for grounds IIRC. (I haven't seen Simutrans code since 5 years, so I don't know much about the current code).
If this is the way to go, I'd like to have the MapColor syntax expanded, maybe like colors are often denoted in web applications:
MapColor=#RRGGBB
Would still be cool if Simutrans could precalculate the colors from the textures :)
Simutrans can still only use only the 256 predefined colors for the map.
