Notes on Different Meanings

The two core definitions are closely related but applied in different contexts: 1. The first meaning (to make/become black) is general and can apply to any object or substance changing color. 2. The second meaning (to convert/infiltrate with melanin) is specific to biological processes involving the pigment melanin, such as tanning, animal coloration, or certain pathological conditions.
