Better RCI Colors 2.1

This mod replaces original RCI colors with more distinctive ones. I don't know for you, but in the vanilla game, I often struggle to see if industries and commercial areas are covered by my depots correctly. Of course I use the cargo layer but due to the original RCI color choice, it's pretty hard to see for sure which buildings are correctly covered and which are poorly. So I looked for it and finaly found the RCI color settings to improve each area tint and make clearly visible which area is which and which buildings are delivered with goods or not and at which level. Enjoy. Note : in order to fix compatibility with outdated mods, it's better to move this mod at the end of your mod list. latest update : fixed "layers = nil" crash when used with outdated mods
