Red - Mature

: Postmature infants (born after 42 weeks) may have skin with a purplish-red hue (acrocyanosis) or a "harlequin color change" where half the body appears bright red.

: Immediately after birth, a woman experiences "lochia rubra," which is bright red vaginal bleeding that typically lasts for the first 3–4 days.

: They develop from stem cells in the bone marrow. During the final stages of maturation, they shed non-functional proteins and undergo "membrane microvesiculation," a regulated process that removes old or damaged components.
