Why stool color matters

Stool gets its normal brown from bile and the breakdown of food as it moves through your gut. Most color changes are harmless and tied to diet, but a few can signal something worth checking. Knowing which is which brings peace of mind.

Alongside consistency on the Bristol scale, color is a simple daily signal. Settle lets you note both quickly, so unusual changes are easy to catch and — if they persist — easy to show a healthcare provider.

Stool colors and what they can mean

Brown — the healthy default

Normal stool ranges across shades of brown thanks to bile. This is what you'll see most of the time on a healthy diet.

Green and yellow

Green can come from leafy vegetables or fast transit; yellow, greasy, foul-smelling stool may indicate excess fat and is worth tracking if it persists.

Red, black, and pale — worth attention

Bright red may be dietary or from the lower gut; black and tarry, or pale/clay-colored stool, can signal issues that deserve prompt medical attention. Settle is not a medical device — if you see these consistently, contact a healthcare professional.
