You ask excellent questions. The color of fecal matter depends mostly on what is eaten as well as general liver, gall bladder, and colon function.
More important than comparing shades of poop to internet pictures or even friends and family, we ask, is there a new difference in YOUR normal color of poop that can be attributed to changes in diet (beets, for example, make stools reddish), physical health (better exercise program, infection, or congestion), and good hydration (enough liquid intake for your environment, physical activity, and other health issues).
A healthy stool is often described as tan-brown, easily eliminated (without straining), and curling 1- 1 1/2 times around the toilet bowl in the a.m. Meat makes stools darker; a vegetarian diet makes tools lighter.
In any case, when in doubt, try one or our mildest cleansing kits (such as 5 day with normal food intake) to see what colon cleansing might do for you.
