Universal Seasons is a set of resourcepacks, that allows you to choose between different seasons in Minecraft. The different seasons result in different colors applied to grass, plants, and leaves. Since the seasons are biome-specific, each biome features other color gradients.

Since it is using the custom colormaps feature introduced by OptiFine, this resourcepack requires an installed version of OptiFine.

As the name already says: Universal Seasons is universal! This means that Universal Seasons is compatible with all resourcepacks, that use “tinted” textures for their organic textures. It can be used as an add-on and can be added on top of the preferred resourcepack.

Of course, this pack also works with the default Minecraft textures!
