This is a small package that adds the color based fog for the Unity's Sprite Renderer component.
To use this just add the SpriteFog material to your SpriteRenderer component and add the component SpriteFog to your gameObject.
Now just pick the base color and the fog color, you can also add the component GlobalSpriteFogColor in any gameObject of the scene to use a global color to the fog.
The Distance field controls how much affected by the fog this sprite is.
We created a small scene where the fog color is changed from day to night and some rain start to fall down
