Change Finder Background
Today I sent a print screen and someone asked me “hey your background is so cute! how did you do that?” Here is the answer… 
First open a Finder window, you can do this in all your background folders too.
I have different backgrounds in some! For me, is nice because I choose a color label and the background inside the folder matching! Is so colorful 
Ok, in the folder you want to change right click inside and “Show View Options”.
In there, you see “background” options!
You can paint with a color, or select a picture (the one i’m using on the screen shot).
There’s also another options in this menu! Actually, you can control de icons size, the space between them, or even show more info about the stuff you have on that folder.
Finally, it’s easy to browse a nice picture to colorize your boring folders
