Tinted water and red sheeps in Dappled Forest

Water in the Dappled Forest should be a slight brown/orange color due to an excessive amount of tannins leeching out into the water due to the many dead leaves on the ground. Also as more of something fun and less realistic, sheep that spawn within the Dappled Forest may have red, orange, and yellow wool. Perhaps if you'd apply some logic maybe sheep that eat the orange tinted grass inherit the tannins into their coat.
