Breast milk comes in every shade from blue to yellow, green, and even pink — and most of the time, it’s completely normal.
Color changes can reflect what you eat, how your milk is stored, or even where you are in a feeding. Foremilk may appear bluish, while milk rich in fat often looks creamy yellow. Occasionally, a pink or rusty tint can result from tiny amounts of blood as tissue heals, and green hues are often linked to leafy greens or certain supplements.
Every color tells a story — and while most are harmless variations, any sudden, persistent change (especially black or red milk) is worth checking in about.
At The Lactation Clinic, we believe in evidence-based reassurance. Our goal is to help you understand what’s normal, what’s not, and when to reach out for support.
