Minecraft skin changes to monochrome browns

The skin I use loaded in a couple days ago as a monochrome brown style and is now stuck looking like such. For my skin, I always have the red flannel equipped with shorts and boots. All of these items now appear in the brown monochrome fashion. Even when trying to change clothes, such as changing the shirt to a different one, the new shirt will also change and look brown monochrome. I tried creating an entirely new character and at first it worked, the clothes stayed as they are supposed to be. However, when I loaded in the following day, my new character also then was stuck in monochrome brown. Most of the pants when stuck in the brown monochrome look as if the character is not wearing at all.
