Why mundane human stool is ashen color? where on earth the color come from?

Recently I had observed patients stool's color, which is typically yellow. While after co-lyte drinking to clear the digestion system and nil left contained by colon or intestine, patients starts discharge water, but still within a yellow color.
Why other yellow color ?
I guess near are micro-communities inside digestion system and it is yellow color.?Why mundane human stool is ashen color? where on earth the color come from?
Stool contains bile salt, which include degraded compounds from old blood cell; this gives it some level of yellow color. Other colors come from food and bacterial doings; and yes, most bacteria are yellowish surrounded by color as well.
It's not really ashen, it's a red tint from the red blood cells that are discharged through the fluent body's system.
The normal color of the stool is brown but change through other chemical actions.

"4. Gray stools, pale stools, putty or clay colored stools may be see in hepatitis, gallbladder disorders, or malabsorption conditions. Bile salt in the stool excreted by the liver make available it a normal brown color. Obstruction to bile flow out of the liver (you may see the word "cholestasis"), or liver infections similar to viral hepatitis (A, B, C, etc.), may produce clay colored stools. Possible causes for clay colored stool result from problems within the biliary system (the drainage system of the gallbladder, liver, and pancreas): Malabsorption problems can cause undigested cooking oil in the stool (steatorrhea) which is characterized by foul smelling, buoyant yellow to gray, greasy or frothy stools. This may also be cause by low bile output."
