Hello All,
This is my very first Stardew Valley Mod, and actually my first video game mod of any sort. I am hesitant to call it a 'mod', mainly because it required no coding at all! 

Anyways, this mod provides replacement 9 XNB files, which change the appearance of various game assets.
I made this mod with my personal style in mind, and my favorite color is blue! (as you soon will tell)

To install these mods,

1. Locate the file you wish to replace, and create a backup. 
For example: Craftables.xnb can be found at
C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\Content\TileSheets\Craftables.xnb
2. Replace the original file with the corresponding replacement file.

Thats it!

The 9 modified files are:

-Craftables
provides colorful replacements for most crafting machines, the scarecrow, and the flamingo
also yeah, the scarecrow is a modified knight
-dog
        makes the dog blue!
-Duck
        makes the adult ducks blue and black
-horse
        makes the horse funky 
-houses
        makes all three houses blue and black themed
-Pig
        makes the adult pigs blue!
-Rabbit
        makes the adult rabbits reddish orange
-Shed
        makes the shed blue and black themed
-Stable
makes the stable blue and black themed


I have used all of these replacements on Stardew Valley 1.3.20
Feel free to ask any questions.
