I was finding it difficult to separate the Japanese and Chinese unit counters, which are all a similar background colour. I find the alternative colours easier to interpret.
You might be able to change unit counter colours in the editor, but I haven't got that far, so this is just a 'cut and paste' job in the scenario units.png file.
The existing Retro map mod terrain.png from Warplan Europe, gives a cleaner map appearance, rather then the graphic look of the stock map. This is a World size map and I wanted it to look more like a map, rather than a tactical graphic. The effect is more subtle and the terrain types are not so obvious, but the game has other data to confirm the terrain types.
