What does period blood color mean?

Bottom linePeriod blood color mostly reflects how old the blood is: bright red is fresh, dark red is slightly older, brown or black is oxidized (common at the start or end), and pink is blood mixed with fluid or ovulation spotting, all usually normal; gray or foul-smelling orange discharge can signal infection, and any bleeding after menopause should be checked.

Period blood changes color through your period, and most shades are completely normal. Color mainly reflects how old the blood is and how fast it's flowing.

What the colors usually mean

• Bright red: fresh, steady flow, often mid-period
• Dark red: slightly older blood, common on heavier days or waking up
• Brown or black: older, oxidized blood, typical at the start or end
• Pink: blood mixed with cervical fluid, light flow, or ovulation spotting
• Orange or gray: can signal infection, especially with odor or itching, worth a check

When color is worth attention

• Gray discharge, or orange with a bad smell (possible infection)
• Very pale, watery bleeding that's a new change
• Any bleeding after menopause
• Unusual color with pain, odor, or itching

The bottom line

Red, dark red, brown, and pink across a period are all usually normal. Gray or foul-smelling discharge is the main color flag for infection.
