If you’re referring to seeing blood or an unusual color when using the toilet, it can be a warning sign that shouldn’t be ignored.
Black, tarry stool: can indicate bleeding higher up in the digestive tract and warrants urgent medical attention.

Bright-red blood: can come from hemorrhoids or an anal fissure, but it can also have more serious causes, so unexplained bleeding should be checked.

Red, pink, or brown urine: visible blood in urine should be medically evaluated even if it’s the first occurrence and there’s no pain.

A large amount of blood, clots, ongoing bleeding, fainting, severe dizziness, or weakness: seek emergency care immediately.

Some foods, supplements such as iron, and medications can also change the color of stool or urine, so color alone doesn’t establish the cause.
If you tell me exactly what you noticed in the toilet (black stool, bright-red blood, red urine, mucus, etc.), I can explain what it could mean and how urgent it is.
