In hospital operating rooms, dermatology clinics, and cosmetic surgery centers, healthcare workers wear medical scrubs of various colors. These colors are not chosen randomly but follow a scientific hospital color coding system that influences clinical performance and patient safety.
This article will introduce the various colors of medical scrubs and explain the logic behind the hospital’s color differentiation.
Different Standard Medical Scrubs Colors
Green and Blue-Green Medical Scrubs
Scientific Background
Green is the complementary color of blood and red tissue. When clinicians stare at red tissue for hours during prolonged surgery, their eyes develop a red afterimage. Green fabric can neutralize this visual residual, thus alleviating severe eye strain, improving the precision of delicate surgeries, and reducing the risk of surgical errors.
Historically, white surgical gowns were used in all operating rooms before 1914. After surgeons discovered that white exacerbated visual fatigue, they switched to green, a standard that was quickly adopted in medical institutions worldwide.
Advantages and Disadvantages
Green is better than white at masking splashes of blood, iodine, and bodily fluids. From a psychological perspective, green is associated with calm and healing, helping healthcare workers remain stable during stressful emergency room shifts.
Dark green fabric, if worn in multiple layers in an overheated operating room, may cause heat buildup.
Best for
Surgeons, operating room nurses, emergency room staff, and veterinarians.
Blue Medical Scrubs
Scientific Background
Hospitals use two different shades of blue to distinguish different work roles.
Color psychology shows that blue naturally builds trust and alleviates patient anxiety, making nervous visitors more willing to communicate with the medical team.
Light gray is a cool shade similar to blue, with lower saturation, avoiding overstimulating sensitive patients.
Advantages and Disadvantages
Dark royal blue helps maintain focus during long hours of continuous work and covers minor stains more effectively than white fabrics.
Light sky blue easily reveals small stains, while light gray requires frequent bleaching to maintain its shine.
Best Suitable Personnel
Dark royal blue is suitable for registered nurses.
Light sky blue is suitable for nursing assistants, intern nurses, phlebologists, and laboratory technicians.
Light gray is suitable for staff in geriatric and psychiatric wards.
Soft Pink and Pale Purple Medical Scrubs
Scientific Background
Warm and soft shades can ease the tension of a medical environment and reduce children’s fear of examinations and injections. These warm shades can also soothe postpartum parents receiving maternity care.
Advantages and Disadvantages
Creates a comfortable and welcoming atmosphere for vulnerable patients. However, the light pink and pale purple fabrics are prone to fading after contact with disinfectants, blood, and bleach, causing the uniforms to fade over time.
Best Places to Apply
Pediatric wards, neonatal intensive care units, maternity wards, and hospice care units.
White Medical Scrubs
Scientific Background
White was the original color for medical uniforms, long symbolizing sterility, cleanliness, and clinical professionalism. It reflects light, creating a strong visual contrast that amplifies the visibility of residual blood during surgery.
Advantages and Disadvantages
White surgical gowns are suitable for medical environments with high cleanliness requirements. However, even small amounts of liquid stains or bloodstains are highly visible on white fabric. Furthermore, frequent use of medical-grade ultraviolet disinfection can cause white fabrics to yellow over time. These are the disadvantages of white.
Best Places to Use
Dermatology clinics, dental clinics, and medical reception teams.
Scientific Background
Black can cover most bodily fluids and chemical stains, reducing visual disturbance during direct contact with patients. The smooth lines of black can also create a sophisticated and upscale visual image for beauty clinics.
Advantages and Disadvantages
They can cover almost all stains without requiring an immediate change of uniform after a tedious cleaning process. However, black fabric tends to trap heat, potentially leading to overheating.
Navy blue, on the other hand, balances stain coverage with breathability.
Best for:
Medical spa staff, clinic managers, and hospital environmental services teams. Navy blue is ideal for extended periods of wearing protective gear.
Maroon Medical Scrubs
Scientific Background
Of all colors, maroon is the best at covering stains, completely concealing large amounts of blood and bodily fluids spilled during complex surgeries and maternity care.
Advantages and Disadvantages
In dirty, heavily polluted environments, maroon can serve as a reliable backup uniform.
However, a drawback is that dark colors might make pediatricians feel heavy and serious.
Best Uses
Operating rooms and maternity wards (can be used as backup emergency uniforms)
How to Choose the Medical Scrubs Color
First, follow the hospital’s official guidelines, as most public healthcare facilities require different departments to use specific colors.
- If you work in surgery or the emergency department, it’s best to use green or turquoise. This can protect your eyesight during long procedures.
- If you want to avoid frequent cleaning of stains or bodily fluids, navy blue, burgundy, or black is recommended.
- If you serve pediatric, gynecological, or geriatric patients, light pink or light blue can be used to provide a gentler experience for patients.
- If your daily work involves frequent contact with blood, disinfectants, or ointments, avoid pure white.
