jetblack

Jet black is a color term used to describe an exceptionally deep black, closely resembling the appearance of the mineral jet from which the name derives. The phrase emphasizes the absence of perceptible color hues, yielding high visual darkness under most lighting conditions. In practice, materials labeled jet black achieve near-total light absorption, though no pigment can absorb all light perfectly.

Historically, pigments marketed as jet black originated from carbon-based materials such as charcoal or coal tar derivatives. Modern jet black inks and pigments often rely on carbon black or synthetic black pigments designed for high opacity and consistent depth. In color theory, jet black is not a standardized shade on its own; it is defined relative to other blacks, sometimes with a cool blue undertone or a warm brown undertone depending on the lighting and substrate.

In use, jet black is common in fashion, interior design, branding, and electronics, where it signals formality, elegance, or modernity. Designers balance jet black with contrasting colors to preserve legibility and visual interest, particularly in text and user interfaces where extreme darkness can reduce readability.

Cultural associations of jet black include sophistication, mourning, and stealth, though these connotations can vary by context and culture. See also black, true black, and off-black.
