I don't. My shits are anywhere from yellowish brown to medium brown to dark brown to light black.

Shade
The color of stool can vary dramatically and can also be a clue as to whether various disease states are present.
Normal stool is brown due to its composition: bacteria, water, bile, bilirubin, broken-down red blood celIs and indigestible plant matter like cellulose, along with small amounts of protein and fat.
Size
Size matters. Small, hard stools are typical in people eating a low-fiber Western diet, and are associated with a higher risk for ultimately developing diverticulosis and colon cancer. Constipation is often associated with small, difficult-to-pass stools, and people suffering from constipation-predominant irritable bowel syndrome (IBS) are particularly prone to having small stools. A high-fiber diet or regular use of a bulking agent like psyllium husk will lead to larger, softer stools in most people, making defecation easier. Even though a fiber-deficient diet is the most likely culprit, colon cancer is again on the list as most lethal.
Smell
The odor of your stool is highly dependent on a number of factors, including how long it's been sitting in your colon, your diet, medications you may be taking and, in some cases, the presence of infection. Bacterial imbalance (dysbiosis) in the GI tract and undigested fat can also lead to a change in odor.
The most common cause of smelly stool is bacterial fermentation of the food in your intestines that produces foul-smelling sulfide compounds. Antibiotics can also change the smell of stool and give it a medicinal odor. More lethal causes of malodorous stool, and fortunately much less common, include inflammation of the pancreas (pancreatitis) and pancreatic cancer. Both these conditions can result in floating, foul-smelling stool with an oily sheen.
