Black nitrile gloves are popular for sleek color. Quite frankly, black nitrile gloves provide no extra benefit compared to other colors you can find: blue, purple, or green. The black color is a dye and any manufacturer can produce these colors. However, black gloves will cost more because this color is more expensive compared to others.
Black gloves made from nitrile are popular among non-medical areas like salons and industrial use. In addition, police officers have been found to don black nitrile gloves since it matches their uniform. In my experience, I haven’t seen black gloves used in health facilities as the color may appear threatening to patients.
