Version 2.1 - edited a few spring fields
This mod doesn't use any new textures, just tweaks of hue and brightness, mainly the forest background was darkened to blend with the trees. Changes spring, summer and autumn seasons. Most changes are done to the spring textures, where I also slightly desaturated the yellowish fields, winter was not tweaked at all.
To edit the mod further, go to ShadingOptions.lua in "Darker Normandy\Mods\terrains\Normandy" and change the first three gamma values. Lowering the numbers will make the map darker.
