Black sheep replacer. Gave it slightly brown eyes and a pinkish nose to add some character, should have the bugs worked out but let me know if you encounter any odd discoloration or inconsistencies that I may have missed. 

EDIT: 3/30/2016

I have fixed the weird crystals that appeared in caves and altered the fabric to be black as well. Loom will still be white since I don't want to replace a lot of the craftables mods that other people have. If anyone with a craftables mod wants to add the black wool idea to theirs as an options you are more then welcome to! <3

How to install:
Download the file, unzip and place into the content folder for Stardew Valley. Should be located on in C:Program_Files/Steam/Steamapps/Common/Stardew_Valley

Be sure to make a backup of your old files! The easiest way is to copy your 'Content' folder and rename is to something like 'Content Original' or 'Content Vanilla'. 

How to uninstall:
If you have installed this mod manually and want to use the vanilla version again, replace these files from your original from the backup that you have made. Replace these files:

Animals Folder:
Sheep.xnb
BabySheep.xnb
ShearedSheep.xnb
Springobjects.xnb

Maps Folder:
Springobjects.xnb

 If you have forgotten to make a backup, NO WORRIES! Simply delete the files listed and make a copy of your content folder (put on the desktop or somewhere outside of the stardew stream folder). Go to your library and right click Stardew Valley, select Programs and Local Files. Verify integrity of game cache and after this runs and completes you should have all the original vanilla files restored. Use the copied content folder without the mods that you no longer wanted to bring back the mods that you wish to keep. simply drag it back and everything should be good as new. 

Other Mods I have created:
