Baby Poop Color Chart: What Each Color Means (Newborn Guide)

The first diaper of the day can look like a science experiment. Newborn poop runs through a startling range of colors in the first weeks (black, green, mustard yellow), and most of it is normal. The trick is knowing the handful of colors that warrant a call to the doctor.
Use the chart below as a quick reference, then read on for what each color means and the three you should never ignore.
Baby poop color chart
Match what you see to the closest color. The colors are approximate, since lighting and diet shift the exact shade, so go by the overall hue rather than a perfect match.
Black & sticky (meconium)
Totally normalYour baby's first stools, in the first 1-3 days. Tar-like and hard to wipe. This is meconium clearing out, as expected.
Mustard yellow & seedy
Totally normalThe classic breastfed stool from about day 5. Soft, loose, and flecked with little 'seeds,' a sign feeding is going well.
Tan to brown
Totally normalCommon in formula-fed babies and after starting solids. Thicker and more formed than breastfed stools.
Green
Totally normalUsually harmless. Iron-fortified formula, supplements, or faster digestion can turn stools green. Look for other signs of illness before worrying.
Orange
Totally normalA normal variation, often from pigments in milk or, later, foods. No cause for concern on its own.
Bright green & frothy
Usually fine — mention it if it lastsAn occasional frothy green stool is fine. If it's persistent in a breastfed baby, it can point to a foremilk/hindmilk balance worth mentioning at your next visit.
Red or bloody
Call your doctorStreaks or specks of red can be blood. Sometimes it's a minor anal fissure or swallowed blood from breastfeeding, but always have it checked.
White, pale, or clay-colored
Call your doctorChalky, pale stools can mean the liver isn't releasing bile properly. This needs prompt medical attention; call your doctor the same day.
Black (after the first few days)
Call your doctorOnce meconium has passed, black stools can indicate digested blood from the upper digestive tract. Get it evaluated.
The normal colors, explained
For the first few days, expect black, tar-like meconium. As your milk comes in, stools move through greenish-brown transitional poop and settle into their everyday color: mustard yellow and seedy for breastfed babies, tan to brown for formula-fed ones.
Green worries a lot of parents, but it’s almost always benign: iron in formula, a passing tummy bug, or quick digestion. Orange and brown shades are normal too. As long as your baby is feeding, gaining weight, and otherwise content, the day-to-day color of healthy poop isn’t something to track anxiously.
The three colors to never ignore
Pediatricians sum up the warning colors as red, white, and black:
- Red: possible blood. Often minor, but always worth a call.
- White or pale/clay: a possible sign the liver or bile ducts aren’t working properly. Considered urgent.
- Black after the meconium stage: possible digested blood.
If you see any of these, contact your pediatrician. The American Academy of Pediatrics (HealthyChildren.org) and the NHS both flag these colors as reasons to seek medical advice.
What matters more than color
For day-to-day reassurance, consistency and frequency tell you more than a single odd color. Steady wet and dirty diapers, soft stools, and a comfortable baby are the signals that feeding is working. A one-off green or orange diaper rarely means anything. A sudden, lasting change, especially alongside fewer wet diapers, fussiness, or a fever, is what’s worth flagging.
When you do need to describe a pattern to your pediatrician, “I think it changed a few days ago” is far less useful than a record of when diapers happened.
